Another fine point, Darkstar2.
Just the other night I went back into my kitchen for another slice of pizza.
To my amazement, nothing was left but crumbs. I am sure I did not eat
that last slice of pizza. Oh yes, my belly was full but indeed doody doo, I
am confident I did not eat that last slice of pizza.
I am most sure that a Martian, Jupitarian, or a Venusian, ate my last slice
of pizza when I was not looking. I did run to my window but what did I see?
Nothing, I did not have my glasses on and I am nearsighted. Still, I am very
sure it was a creature from outer space.
Perhaps you are correct. Why waste money on space exploration. Let the
aliens spend the money and come to us. All we need to do, is work on a
good capture plan. And since I know they like pizza, we'll trap them with a
slice!
