Anyways here is the jist of how it worked. It is a little more complex than ill explain
THe basic building block for animals is cells, and of cells it is amino acids. Earth's early atmosphere was very volatile containing high amounts of CO2, methane and ammonia. Up until now it was unknown has to how the first amino acids wereformed. But this was all figured out in a lab. When you take the earths old volatile atmosphere and charge it with intense electricity (as in lightning) and throw in some other variables, traces of amino acids form. These amino acids attract and form cells (similar to the way gases form stars) So from this reaction in early Earth the first cells formed. These cells (such as algae) photosynthesized the CO2 into oxygen allowing for animal cells to evolve.
This is basically how it happened. So once again I have disproven Creationism, although most of you will deny it.
It was all figured out in what lab, by who? I hate to burst your bubble when you're feeling so smug but here goes.
From 1980 on, NASA scientists have shown that the primitive earth NEVER had ANY methane, amonia or hydrogen to amount to anything. Instead it was composed of water, carbon dioixide and nitrogen---- and you absolutely cannot get the same experimental results with that mixture. More recent experiments have confirmed this to be the case. (That pretty much ruins your made-up theory, but there's more)
We could assume for amusement's sake that maybe one-celled organisms are more complicated today due to the fact that they have been developed and evolved through the eons. Maybe the first cells produced on the primitive earth were much more basic and therefore easier to create.
If we assume that theory, it is still not simple to build a living organism. Essentially, you start with amino acids. They come in 80 different types, but only 20 of them are found in living organisms. The trick is to isolate only the right amino acids. Then at the same time, the right amino acids have to be linked together in the right sequence in order to produce protein molecules. I think of those plastic stick-together chains that kids play with....you have to put together the right amino acids in the right way to ultimately get biological function.
But, there are still more complicating factors to consider. Other molecules tend to react more readily with amino acids than amino acids react with each other. Now you have the problem of how to eliminate these extraneous molecules. Even in the Miller experiment,(Stanley Miller at the University of Chicago) only 2% of the material he produced was composed of amino acids, so you'd have a lot of other chemical material in early earth to gum up the process.
Then there's another problem: there are an equal number of amino acids that are right and left handed, and only the left-handed ones work in living matter. Now you've got to get only these select ones to link together in the right sequence. And you also need the correct kind of chemical bonds---namely, peptide bonds--- in the correct places in order for the protein to be able to fold in a specific three-dimensional way. Otherwise, it just won't function.
You can picture a printer taking letters out of a basket and setting type the way they used to do it by hand. If you guide it with your intelligence, it's no problem. But if you just choose letters at random and put them together haphazardly, including upside down and backwards, then what are the chances you'd get words, sentences and paragraphs that would make sense? It's not just unlikely, it seems impossible!
In the same way, perhaps 100 amino acids have to be put together in just the right manner to make a protein molecule. And that's just the first step. Creating one protein molecule doesn't mean you've created life. Now you have to bring together a collection of protein molecules with just the right functions to get a typical living cell.
Now the biggest problem of all: in living systems, the guidance that's needed to assemble everything comes from DNA. Every cell of every plant and animal has to have a DNA molecule. You can think of it as a little microprocessor that regulates everything. DNA works hand-in-glove with RNA to direct the correct sequencing of amino acids. It's able to do this through biochemical instructions, that is, information that is coded on the DNA.
The making of DNA and RNA is a much greater problem than creating protein because they are much more complex and come with a host of practical problems. For instance, the synthesis of key building blocks for DNA and RNA has never been successfully done except under highly implausable conditions without any resemblance of early earth.
Klaus Dose of the Institute for Biochemistry in Mainz, Germany, admitted that the difficulties in synthesizing DNA and RNA "are at present, beyond our imagination."
Nobel Prize-winner Sir Frances Crick said, "Frankly, the origin of such a sophisticated system that is both rich in information and capable of reproducing itself has absolutely stymied origin-of-life scientists. The origin of life appears to be almost a miracle, so many are the conditions which would have had to be satisfied to get it going."
So, I think, once again you've proven that you don't know what the h*** you're talking about! Don't come on here and try to b*** s*** your way into convincing anyone that you or anyone else can PROVE evolution is absolutely irrefutable. Tha FACT is that no one knows! I choose to believe in creationiism because it makes more sense to me. And as I've stated elsewhere, there is also room for some evolution in my belief, but not macro-evolution!!!!
