The Chemistry of Life Is Like Tetris

In order for the chemistry of life to happen everything has to match which means you need like all the pieces to have the right chirality. You can't mix and match left and right-handed chemistry of life yeah that's why i fist-bond people when i meet them these days it's just too confusing but i was thinking  it's sort of like tetris right like in tetris you have pieces and like every piece in tetris is made out of four blocks but depending on how you put them they're symmetrical or not. We think that probably universe is symmetric in that it would allow for life to have both chiralities but we don't actually know
