Basically I’m aware of how Big Bang led to expansion of universe, gases, atoms etc. But how did some presumably basic radiation/heat mechanisms lead to literal organisms that had life? It doesn’t make sense to me.

Think about the human brain. The brain is made up of a huge number of molecules arranged in a specific way. If you were to randomly shuffle those molecules 100 times, what’s the probability you’ll create a functioning human brain? Pretty much zero, or close to it. Now instead, consider a very very primitive single-celled life form. Essentially just a basic cell that is able to use energy around it and replicate itself. Compared to the brain, it is much more likely you could recreate this single cell by shuffling its atoms around, especially if you had a really really long time to do so.. The conditions we believe are necessary for life to evolve from dead matter involve high temperatures, pressures and lots of chemical reactions. Our leading theory is that at some point life began deep in the ocean near thermal vents. This is a place where lots of the right molecules are in the right place and they are constantly getting shuffled. Over a long enough period of time and stability, it just so happened that life appeared out of dead matter
