I dont think we are alone in the universe though.
Strangely I think I read that physics doesnt forbid time travel so who knows if we have or are being visited.
There was a book I read years ago called
'Was God an astronaut'
Interesting theories on Easter island and the like.

Alien life exists in the universe as the chances of it being a once occurrence is mind boggling when you consider the size of the known universe and how long it's been about - 13.7 billion years is the current number.

It's more about the first emergence of 'intelligent' space capable life somewhere....or how common that is.

The big hurdle is of course going from single cell organisms to multicelluar......that's a massive leap....at some point a cell survived and adapted after being...presumably swallowed by another cell....that's mind boggling in of itself.....without that we couldn't be here as complex functioning systems couldn't emerge.

How often does that happen?....ah, one of the great unknowns.

For me, evolution means that once you have complex animals who can survive and reproduce successfully I think 'intelligence' will automatically evolve as a survival requirement....social animals are more successful than non social.

In my view there would have been 'intelligent' dinosaurs....in the same way some birds or sea creatures are intelligent.

We have had the odd discussion about UFOs on here and I have previously said that my personal experience and what I have been told leads me to believe that we really have been visited by someone from outside of our realm.

This interview was posted in December 2017 and I'm really surprised that it didn't cause more of a stir.

It just confirms my suspicions about what might happen when people are eventually confronted with 'official' proof.

Many will just ignore it.

Life is out there. There is virtually no chance of us being alone.
Our solar system appears to be unusual judging by what we have observed. The Earth perhaps more so.

That might mean that intelligent life like ourselves could be very infrequent. That does not mean that we are not being visited. There are almost infinite possibilities.

The problem with this subject is firstly, the loony factor. If you talk about it, you are likely to be branded a loon, and there is no doubt that the subject does attract some nut cases.
Second. Trying to apply logic to a subject which has no certainty. Despite some trying to appear 'informed', it is impossible to make educated judgments about a subject about which there is no understanding.

I can believe in intelligent alien life what I don't believe is that they travel thousands of light years to this planet not make formal contact and spend their time whizzing around Area 51 or whatever.

What is the point of that. If they want to observe us I would think they can do that from orbit.
