Astronomy

Personally I find this very probable:

First, the big bang happens and stars are made

Then a star large enough to fuse heavier elements needs to live its full life then die of a supernova to create elements heavier than iron

Lastly those remnants need to form a new solar system with a planet somewhat rich in these heavier elements to support life, as well as the time needed to have life spring up in the first place

In terms of how long all of these take, we're pretty young cosmically
