Oc. The only problems are time and space.... others might be long extinct or just aren't envolved if we go there. And then there is obviously the space. The universe is so vast... before we reach another planet with liveforms on it we might be long dead.
And the universe expands faster than the speed of light. That means that even if they existed 13 billion years ago and found a way to get light to us we might not see them because the light will never reach us.
bennile 📚, "Edwin Hubble was the first to measure the expansion rate. The number he got was way wrong, so I won't bother mentioning it, but good on him for trying. The more modern value is 68 kilometers per second per megaparsec, plus or minus a couple, but close enough." Jun 29, 2016
bennile 📚, it's not a mistake...if you measure how many megaparsecs there are and multiply them by the expansion rate originally set by Hubble....you exceed the speed of light. It's possible in the special theory of relativity as well. I was agreeing with your statement 😉
It's "possible" but it's speculative. When you look at the vastness of the universe it's tempting to say yes the odds are huge. But then when you study all the little things that make life possible, including the magnetic field that protects us from radiation, the ozone layer, and the random chance for clay to form the first DNA electrostatically, then the tiny lipids that surrounded it, and its strange ability to recreate itself....the odds of it even happening here were nearly impossible....we beat incredible odds just to form the first cell that ate and reproduced itself. Then add on top of that the odds of it being able to mutate....wow just think about how nearly impossible it is that WE even exist!
