Of course, but there is no doubt he truly believes that there are/were thousands or millions of civilizations...not because we've found evidence, but because there are an innumerable amount of stars, so by sheer chance and number, there are planets that are inhabited by intelligent life. Clearly, this is belief without evidence.
I didn't know the answer, years ago. But then I recalled that there are billions of planets in this galaxy alone, and billions of galaxies. The scale of universe makes it reasonably possible for life to exist, even thousands or millions of planets with life.
I think the word "civilization" that I used is wrong. It might very well be, but then I assume a specific kind of animal, instead of just life. I'm sure if I want to make similar guesses about that, but I think there might be a few in that HUDF picture, and quite certainly in the whole universe.
This is like saying that if I blow a paint shop up countless billions of times, I would get a Mona Lisa "thousands or millions" of times. It's highly improbable that you would get just one.
Nope, the analogy is more like blowing up a paint shop 10^24 times and you know that there is at least 1 Mona Lisa. Would you bet there are more than just that one (don't confuse the probability of the paint shop with the universe)?
It takes more faith to believe that than it does to believe in God.
Nope, because life has formed at least 1 time in the universe, but there are still 0 gods that we know of that exist in real life.
..but the Universe is almost 14 Billion years old. You mean to tell me that if there were "thousands or millions" of civilizations out there -- potentially -- that none of them had the technological knowhow to find or contact Earth?
I can impossibly comment on that, because you can't tackle this problem with probabilities or so, you have to have experience with aliens to know this, and we don't.
But maybe they might have the technology. But even if there are millions of those searching for other life, the universe is still too big to guarantee they must have visited us. We might be the only intelligent life in the galaxy, or maybe there are another few ones, but they have to search billions of planets.
Image if we had the technology. Would the government allow to randomly waste money on finding maybe 1 civilization by searching in billions of solar systems?
If they came and went as you hypothesize, perhaps even millions or billions of years ago, they had plenty of time to be much, MUCH more advanced than us.
This is the kind of paradox you will always run into even if you hypothesize that there are/were "millions" of dead civilizations that obviously didn't find us first. Saying that they're dead even makes your argument more faith-based because it cannot be falsified.
It's an interesting paradox indeed, but it cannot be solved without experience.
They're dead because that's sort of what happens after about 10 billion years. But if there are indeed civilizations today, we could extrapolate back in time, because I don't know why they couldn't live billions of years ago. Not faith-based.
