The SciFi movies portray deep space as empty, your starship just zooms through it for light years without hitting anything.
The Kuiper Belt would beg to differ...
Just going 6 light years in a straight line is impossible now for humans to survive.
Imagine if your starship, going really fast in space (not air), had to turn and avoid things like asteroids and gas pockets?
I believe in life outside of Earth.
I am just very skeptical that life can get here any more easily than we can get "there..."
