How was protein synthesized from amino acids in the prebiotic world?

Where in the non-living nature can we observe:
“Non-living" nature stands for life just before it appeared on earth. Possibly for life just after it appeared for those who want to believe protein was synthesized only after life first appeared.
Who here at CFI might have the capability, or ability, to observe Earth in its first few hundred thousand years? Excuse me for taking this line of questioning with a touch cynicism. It's simply me thinks you're playing games.
