I mean, say that "aliens" were directed to look in the direction of our Sun, what's the probability even then that they would discover our existence. I just told her that life has existed on Earth for about 4 billion years, I mean, since it formed. Yet only in the past half century or so have we been transmitting any signals of our existence. I just think and I'm convinced that the chances of discovering our existence would be about 1 in 100 million, based on the millions and billions of stars, galaxies, and planets. And this applies only if they knew exactly where to look. UFOs are so fake. |
I don't think it's too far off. You can't assume that any sort of alien life is on the other side of the universe, they could well be within our own "neighborhood". Any sort of alien species could have thousands to millions of years on us in the sense of bio and technological evolution, who knows what sort of technology they have developed during that time.
