We havent met because the galaxy still to big to explore, if they were able to come here its mean their technology is better than us
The aliens in our galaxy might not be in the same form and dimension as ours. Angels and demons are aliens and they've been interacting with humans long before science came to be.
What evidence do you have for that? There is none that I know of. For angels, demons or aliens. But agree with the first part. If aliens exist they may be very different from us.
humans already met an alien a new species not known to man is an alien.
and if you mean alien from outerspace then i dont know about that.
Of course that is what he meant. It's what the article is about. And saying other species on earth are aliens to us is not a good way to put it. They may look different but share a lot with us. In what they are made from. How their cells are structured. How they behave. Etc. May not be true for real aliens.
