There are about a billion galaxies, each with about a billion stars. If the odds of life forming on any one of the star systems is only one in a billion, then there a billion planets with life on them. Makes you think.

As for getting here in a flying saucer, I don't think so. When our local Staford Linear Accelerator Center wants to accelerate an electron to near the speed of light, they have to do it in the middle of the night when the electric grid is not being used much, because it takes so much energy to ecceklerate a tiny little electron. So how do you get a massive space ship going fast enough to travel light years across space?

If you can, no problem for the astronauts, because as they go faster, their clocks slow down from our frame of reference, and the distance to places for them contracts. At .99 the speed of light, 100 light years becomes maybe 4 light years for the space ship. (I think, I'd have to do the math, which is actually simple.)
