You're completely ignoring the experiments because it's not what /you/ are looking for aka right now proof.
As I said, personally I have little doubt that they have recreated not only the processes on early earth that started life, but also the process by which cells evolve to multicellular.
But they haven't and the previous post you made tells you they haven't. This is the problem with many people who wish to believe this... you get the cart ahead of your horse. When you start with a conclusion then construct a hypothesis around it to support the conclusion, that is not science and not how science works. It's simply a hypothesis based on speculation.
By your ideology then, technically nothing is proven. I personally prefer to believe that the scientists aren't just "making shit up," if you wish to believe otherwise, that is your choice, as I said.
