Odds of intelligent life occuring?

[Anomalocaris]

Homo naledi was around as early as 335,000,000 years ago. (If you haven't heard about the Rising Star cave and the burials within you need to catch up on this, it's fascinating.)

Think you got too many zeros there.

I'm probably speaking out of turn, I haven't read the whole thread yet, but I just wanted to address this:


The era when this would have occurred was during the formation of the Solar System, when local debris was far more plentiful and collisions far less rare. Even now, collision events happen - just ask Jupiter. Gravity is still a major player.

The LATE HEAVY BOMBARDMENT got it's name from something, just can't recall what. 

The late heavy bombardment is a distinct event 600 million years after formation of the solar system. Nothing comparable to the planet to planet sized collision that formed the earth's moon is known to have happened during the LHB.

Planet to planet sized collisions were probably common during the formation of the solar system. Given that we seem to have at least two examples in our solar system where such collisions seem to have spawned large moons a sizeable fraction of the size of the parent planet, terrestrial planets orbited by large stabilizing moons arising out of early collisions are probably common amongst planetary systems that has terrestrial planets.
