Chemical evolution of amino acids and proteins ? Impossible !!

as if creation was not a possible option... LOL

At one point there was no life on earth. Therefore, if it didn't come from somewhere else, the only other possibility is that it began on earth, originating from something that was not alive in the biological sense. That is abiogenesis. If it was created, and the creator was biological, it came from somewhere else. If it was created and the creator was not biological itself (a spirit or somesuch), the creation of the first living thing on earth was an act of abiogenesis.

The available options are life came from somewhere else, scientific abiogenesis, and unscientific abiogenesis. If you eliminate abiogenesis altogether, the only option is that life came from somewhere else, and that just kicks the question of how that life started down the alley.
