I am not against it, all I propose is that there are other possibilities. But even with that I still think a singularity is possible. However; that is not your question to me here so I'll give you one example of how it could arise without the need for a singularity.
The space within the universe arose all at the same time but not from a fixed point but rather an already enlarged "bubble". The space itself was only a conversion of some type of pre-quantum force. What kind of force, well something similar to a vacuum but not quite a vacuum itself. This force has a critical state within itself, once that state is reached, sort of like a boiling point of water, the force transforms into something else. This something else is the space that we observe. However the energy within this space is still present as a byproduct of the pre-quantum force. So when this "reaction" occurred it wasn't from one fixed point but it span over billions of light years in diameter.
You might ask, where is my support for such a theory. I have one; "the Horizon Problem". Have you ever heard of this problem? If not I'll give a short explanation here.
One problem with the big bang theory is called the Horizon Problem. This problem deals with the microwave background radiation. I hope you are familiar with this concept. If not, well then you might want to check it out.
Basically any direction that you look into space from our point of view, you will see a uniform temperature signature in opposing directions. There is a small discrepancy of only 0.01% which is basically uniform. But you might be wondering, what does that mean.
Well if you take two regions of space that are over a given distance, like 500,000 years apart or more, they are beyond the light transit time, meaning that there is no way regions of space could be uniform because the amount of time it would be required for the "information" to traverse and reach equilibrium does not match the believed age of the universe. It would require the universe to be much much older than it currently is to allow for such a uniformity to occur over such a vast distance. In other words regions of space are beyond each others "horizon". This discrepency is also referred to as the Isotropy Problem.
So if the universe is 15 billion years old then how can you get two opposing regions of space near the edge to be uniform in temperature if their points are more than twice the age of universe? It simply can not happen unless there was another way for the temperature to equalize while the universe was still very small. It would have to be less than 500,000 light years across for the age of the universe to have equalized in temperature. Any larger than that and you would see variations in temperatures.
So with my theory, the universe was not derived from a singularity but instead from a transforming "bubble" if you will. The best analogy I can use to explain what I mean is to use a flammable gas as the example. Lets say you have a gas that fills the entire volume of any given space. Let's say the space is a billion light years in diameter. When the pressure of this gas reaches a certain point it will flash over. When this flash over occurs the entire thing ignites all at the same time. Why at the same time, because the flash over point is the same no matter where you are, because the pressure is uniform through the entire volume.
Now don't confuse my gas analogy with pre-quantum force. Because I can not tell you what the pre-quantum force is. All I can say is that certain "elements" arose and the result of that was the transforming of the pre-quantum force into space-time. So instead of a singularity, the universe actually came into "being" already at a very large size, perhaps a few billion light years in diameter give or take, not sure exactly. Now if this were to happen, the microwave background radiation could still be uniform because like the flash over example, the temperature would have been uniform as the pre-quantum force converted it's "energy" into space-time. The dissipation of the temperature would have been uniform all the way.
Not only that but you can still have an expanding universe even with my theory, yet I have completely bypassed a singularity.

Its possible that the process we observe is not exactly what is really happening. I remember seeing the math done on determining what sorts of observations you would see from within a collapsing star, and according to the calculations you would actually observe it expanding even though from the outside observation you would see it collapsing. Perhaps our observation of the expansion of the universe is similar. Perhaps what is really happening is a contraction but we are observing the bent phenomena for some reason which makes it appear as though it's expanding.
The best way to put this is: We know that if you stretch light wave lengths you can get a shift in color hue. However this does not imply that you are stretching the wave length. It just means you are distorting the wave length in some way. So you could distort a light wave even by compressing it and from a certain perspective you can get it to appear to be stretched even though it is being compressed. How? By bending it around a surface it would actually appear to be stretched.

And I can't think of any evidence that refutes irreducible complexity
One famous example of the theory that was debunked is dealing with some cells like the bacterial flagellum. The ID theory stats that in order for the this bacteria to properly function it requires this sort of complex motor which allows it to spin this whip like tail, which then propels it forward. Without this motor the bacteria would not be able to move, so the argument states that the motor is an example of ID. However; this argument was flawed. Here is a video to explain it better than I would.

So you can argue that a cells modifications are really not that surprising. In fact look at how many different cells the body is made up of. There are over two hundred different types of cells in the human body. Many of these cells do not have the same function nor the same make up as the others. Some are missing certain parts and others have parts that others do not. It really comes down to what the cells function is and how easy it is for it to acquire nutrients and expel waste.

Let me ask you this: How could the cell, the smallest part of life, exist without any one of the components it now has? Because in order to have evolved over time, the cell would have had to, at certain points, been lacking in certain structures in order for those structures to have evolved. (This argument is the basis of irreducible complexity.)
Already explained above. This is only one example, there are more, but to prevent this response from becoming incredibly long I left them out.

Think of how unlikely it is that lightning would struck a puddle of organic slime and cause life to spontaneously arise, on a planet where such life would actually be possible AND sustainable in the long-term.
Well first of all, no one actually says that there
had to be lightning strikes which caused life to arise. From my understanding it didn't happen like that at all. From how I understand it, the process involved moisture and evaporation. So these inorganic particles were brought together in some form of liquid, which then dried up. Perhaps in small pools of water which then evaporated leaving behind a residue. This residue was probably irradiated by the sun and then later this residue was resubmerged in some more water. Think of it raining, then those pools of water dried up and then it rained again some time later. This process repeated a few different times. With the right combination of inorganic compounds and the process of moisture and evaporation, you can actually create the same amino acids found in RNA. We know this because it has been replicated in the lab.

Now add to that the odds of some kind of life arising that would actually be capable of reproduction (which, as I understand it, is necessary for evolution). It seems more likely that life would have spontaneously arisen and then quickly died out, instead of, by chance, also having the unique ability to make more of itself.
You are thinking of it too far down the chain. All you have to do is produce RNA and you have a self replicating molecule, and that's the building block for DNA. It doesn't even have to be in a cell yet. All it has to do is be a block of amino acids that link together. It's very easy to do at this stage because certain compounds stick together while others do not.

One last thought: It seems the Urey-Miller experiment, which set out to prove that electricity COULD cause organic components to come together and create life, did not succeed in proving this adequately. Urey and Miller were unable to create life in a test tube--even WITH the intelligent intervention characterized by the controlled experiment they were conducting.
Yeah some of the attempts failed but the process was re investigated and other methods were used and it has been successfully done. I have already given the example of how it was done above. Through a process of mixing in moisture, such as a small pool of water, then that water completely evaporates, it's compound slightly changes due to being out of water and exposed to the sun or some other heat source perhaps. Then later re submerged into more water and this process repeats a few times. After some time you will get simple amino acids forming within these small pools of water. These simple amino acids can combine to form RNA.
