Seriously, if you are genuinely interested in this, and are not just asking it rhetorically in an attempt to prove a point, ask it on the
science and mathematics forum, and post a link to the thread. It really has doesn't to do with either the historical evidence for, or the theory of, evolution.
To say there's no point discussing evolution until you know how the universe originated is a bit like saying that there's no point trying to build a bridge using newtonian physics until you understand superstring theory.

What do you mean by 'living' in these context? Do you mean 'self-replicating? If so, then me. I observed it, in salt crystals, in GCSE chemistry.

Evolution doesn't say that one type of creature (I presume you mean species) suddenly changed into another. It happens gradually.
Allow me a brief analogue. Imagine evolution as a change in colour, rather than in living creature. In the analogue, imagine we both agree that it is possible for one colour to change very slightly, very slowly. Like a very small move on this spectrum:

We'll call this micro-colour-change.
Now, I say that, given enough time, green can change to red. Call this Macro-colour-change. "Nonsense", you say, "this cannot be observed". You point to a green spot on the spectrum. "Look, green", you say, and we watch it for a long time, and it does change, but rightly you say "well, its a very slightly turquoise-y green, but IT IS STILL GREEN. It hasn't changed into a different COLOUR. And see the red there. Sure, it's changed into a very very slightly pinky red, but it's still RED, it hasn't change COLOUR!".
Do you see the error with this argument? Is my analogue fair, or am I misrepresenting you in some way?
