So what?! This does not prove anything! There are stones all around us, but they don't assemble themselves into beautiful, majestic stone buildings! All ingredients of concrete are around us, but we don't see them turning into concrete and pouring themselves into freeways, bridges, and all kinds of much less complex than living organisms!

I just walked into a room and everywhere I look, everything I see is made up of the same basic building blocks.

The only thing left to figure out is how did these legos learn to assemble themselves.

So what? We are not really experienced in judging how chemical processes work across (a half of) billion year timespan. Or how can intense lighting and volcanic activity across similar timespans affect the probabilities of outcomes. And so on
