So, you're a physicist, waxing lyrical around the stars but being clinical about there being life on Mars.
How topical, how very short sighted and astronomically speaking, how anatomically we're seeking something similar to us.
The very chemicals of extra terrestrials are in our genes (or so it seems) we are just an alien, a species foreign to this shore,a stopping off point to a world of more, so you're a physicist? You must have missed the last bus home.
