We do know this:  On Earth, life seems to have first formed about 600 
million years after the formation of the Earth.  The Earth itself is 4.6 
billion years old.  So that means that life formed on Earth in its 
"childhood".

And I've never heard any plausible argument that conditions on the 
primordial Earth were in any way rare or unique for primordial planets 
the size of ours elsewhere in the Galaxy.

If true, then that suggests that the formation of life on an Earth-like 
primordial planet isn't that difficult.
