Here, probably not.
Here, probably not.
I firmly believe that aliens don't exist. There's no proof supporting their existence.
*More evolved then single-celled organisms, mostly more like plants, bugs, etc. at the minimum
There is no way we are the only intelligent lifeforms in the galaxy. However, if there is a civilization capable of coming to our planet, it seems like the only reason to come here is to conquer us. It'd cost too much in terms of resources, at least the way we know them. If anyone is capable and willing to come here, they are probably capable and willing to kill us all for our world. I'd rather not picture alien life as a super-advanced, Geth-like race that exterminates all that cross their path, but it's pretty much impossible that they'd be benevolent space monks.
Well in that case we may never find proof, because the closest form of life I described could be millions of lightyears away, or just far away enough for us not to notice.
Same goes to the other species. They would be in the same situation, so how would they know we're here? (The more intelligent ones)
By the time an alien species would find us and try to make contact, humanity may already be gone, and they'd only find ruins.
I'm saying that what happens in practice isn't the same as what statistics predict. Just because statistics say that there's life out there, doesn't mean there actually is.
If statistics said life exists, and there isn't, what would that mean?
Just because life may exist, doesn't mean it actually does.
imasillypiggy, there are no statistics!
Since we don't know what the chance of life developing on any planet is, we are left with at least one unknown value. We cannot calculate or estimate anything from that.
Also Jookia, science is all about statistics. We can never prove anything, any theorem or physical law absolutely. We can only test them and verify them by looking at them statistically.
What about intelligent species on Earth for example. Out of the many millions species here today, and the hundreds of millions of species that ever lived, only one intelligent creature has evolved. I say that makes us pretty special and unreplicable.
Here? No. Out there? 99% positive.
about 0.00001 that conditions would be right for life (According to our calculations, and we are most likely way off)
and a ten thousanth of a chance times infinity or near infinity..... that's a pretty good/definite chance.
