Why was hydrogen the first atom in the universe?

528 viewsOtherPhysics

To my understanding, at the very beginning there was the big bang when nothing (or everything?) existed in singularity, and then at some early point hydrogen came to existence. I understand how stars churn with gravity and heat and whatnot those bigger atoms such as iron at later stages of the universe. But how and why did hydrogen happen as the first atom, and why didn’t we have, say, uranium straight from the beginning?

Because uranium is basically a bunch of hydrogen stuck together, can’t have that without hydrogen first.
