As i said intellectual infancy---
to even consider no other life forms elsewhere,
when we are are an atom in the grain of sand in a billion mile desert suggests that man is at intellectual embryo stage..
new planets are being found at a fast rate all within a 100 lights years of us , and as you know, 100 lt yrs is a mere stone throw away from us... dont forget the millions of stars in the milky way alone and the millions of galaxys,
a super nova has been found at 10 billion lt years away.. surely God only made us, its obvious.. sheeesh..
