Many, perhaps most, people believe there is almost certainly life elsewhere in the universe, and even intelligent life, based upon statistics. Not that many believe in aliens on Earth and flying saucers though.
But -- at least 3 US astronauts do believe that aliens have visited us ... Gordon Cooper, Ed Mitchell, and Brian O'Leary. So she's not the first of those who have been to space to "believe".
They are here and they look just like us, except they have a mutated fourth finger that sticks out. They have no heartbeat and when they die they glow red and disappear. I have been waging a war against them since 1967, but few believe me.
Wow, Im interested in hearing about some of your encounters, Im sure the other people on here would as well!
""There are so many billions of stars out there in the universe that there must be all sorts of different forms of life," she went on. "Will they be like you and me, made up of carbon and nitrogen? Maybe not."

Life started on our 4.5B y/o "Goldilocks planet" after only a half billion yrs, ie- pretty "easy" to start life. If only one in a million stars has a Goldilocks planet and if only one in a million of them had life, there'd still be billions & billions (with thanks to Carl Sagan) of planets with life on them. It's a sure thing we're not alone.
Life elsewhere will be based on C, N, O & H just like here. It has to do with probabilities, valence numbers, molecular weights, stereochemistry and The Minimum Principle that pervades physics. That doesn't mean they will necessarily have DNA, proteins etc just like us, but it will be close.

Simple deduction: if they did stand out, we'd know about them, ergo, they must not stand out. Not proof they're here, but IF they are....

The gamblers that do not play the odds at the casinos have to rely on luck and luck takes most into the poorhouse. I am well aware of the odds of life on other planets. The big question is if alien life has found its way to our planet? Of course there is the chance that microbial life hitchhiked here on meteor? But most, on this forum, are looking for something bigger than a microbe. There is a lot of speculation and many think they saw something from out of this world; but we have no proof. Or, I should say, we have no proof that anybody wants to share with us.
If aliens came here for survival I would think they would make there present's known. If they had large mother ships they could launch attacks from space and we would have a hard time fighting a defensive battle. I just don't think they would come all this distance to dance around the maypole. It would be a possibility, but if you look at our history; it is unlikely.

That is true only if you have a very narrow definition of "Life." And that isn't so simple. We may have no frame of reference for the basis of other thinking minds on other planets. Or not. We simply don't know for sure one way or the other.
If you don't want to watch the whole thing, start around the 8:00 mark.
That's just speculation. Sounds reasonable, but some more concrete evidence would be needed to be plausible.
