Taking the scale of just planet Earth, where ever life can exist, it does exist. There's so much life all over planet earth, and so much more that's gone extinct, that because the conditions here on Earth aren't so hard to come by, that it's happened all over the universe is likely. Even if only 1 in 100 billion stars has life similar to our's, because there's a hundred billion other galaxies means there's 100 billion other people similar to us.
On the cosmos they said we don't know for sure when or how life first started. They were theorizing a meteor hit mars and mars rock flew into space and landed on earth and had a stow away microb on it.
How do you think life got started?
As with my answer to what happens when we die, "I don't know" remains my best answer to how life started.
I'd think that once a planet's conditions allow chemistry to take place, raw materials "ferment" becoming new things, eventually becomming organic, eventually becomming life. Then you're off to the races.
