> Emergence of life on Earth took 13.7 billion years

13.7 billion years? Isn't that the age of the universe, and didn't life emerge on Earth only after about a billion years?

[yreg]

Yes, but the parent means we are 13.7B years late to the party. Other civs should have been spawned before Earth was formed.

The formation of Earth wouldn't have been the starting gun for alien life evolving somewhere other than Earth.
