Good topic.
I had to vote "Yes". Reason: well there is an estimated 100 BILLION galaxies in the universe. In each of these there could be anywhere between 1-400 billion stars. And that is just stars and galaxies - doesn't take into account dust, nebulae, dark matter, black holes etc. These are also conservative estimates.
And put some distances into the mix, the closest star to earth (other than our sun) is Proxima Centauri, which is about 4.2 light years away. In terms of AU (Astronomical Unit), where 1 AU is the distance from earth to our sun, this same star is about 260,000 AU away. To put this into a bit of perspective, Pluto is 40 AU away.
Anyhoo, I guess all I'm trying to say is statistically I find it very hard to believe there
isn't life anywhere else. The chances of another system
somewhere having just the right conditions for life are far too high.
And we've not even come close to searching our own
solar system yet, so it makes it hard to draw conclusions about the rest of the universe. In a way it's a bit like searching a square metre of sand on the beach and not finding any 'treasure' then claiming that no treasure exists on any beach anywhere in the world.
And as for them not yet discovering
us just have a look at the distances involved above.
Yes, it's a Monday arvo at work ....
