If I place a grain of rice on the first square of a chess board and double the amount on each step, I'd have 18 quintillion grains of rice.

It happens.
Life started with self-replicating molecules. And ramped up all the way to structures like the human body which consists not just of quintillions of molecules but of billions of quintillions of molecules.
18 quintillion grains of rice? That is not going to happen.
Just for reference, 18 quintillion grains of rice is roughly 500 times the global production of rice in 2022.
