I don't have a belief. I have a knowledge of the distances involved in inter stellar travel and the limitation of the speed of light. I also have seen no evidence of what you believe. I have a scientific reason to understand why we haven't had extraterrestrial life. You are the one with nothing but a belief.
You did the same, giving an opinion or a supposition. You have no more proof than I do. But I know what I saw, and it was not of this Earth. Choose not to believe if you wish, but I know beyond any doubt.
No, I explained why extra terrestrial life can't happen from science. You know beyond your doubt, certainly not beyond mine.
Lol, we are infants in understanding how this universe functions. To say there is no way to travel vast distances because we don't know how to do it, shows an incredible lack of imagination. Without imagination, we would still be in the stone age. I suppose you think we have had physics figured out for a long time now and there is no way any of it can be violated. Time will tell, but I suspect you are way off.
I can only base my thinking on the current state of physics. The current state says interstellar travel is virtually impossible. In order to get me to agree with you, you need to explain in detail why the current state of physics is wrong and you can define a better state. I do agree that we know less about the universe than we think. But what we know is all we have.
Like other objects, they have to be identified in order to not be UFOs. Anyone believing in alien visitation would be a strong advocate of this point. We saw Oumuamua come through our solar system. Serious people thought it could possibly be an alien visitation. It moved in a way that required force, which probably came from off gassing as the object warmed. It was a UFO until enough information was gathered to cause almost every expert to believe it was simply a rock that arrived from someplace outside our solar system.
Okay. I guess I don’t see your point. Some UFOs eventually get identified as meteors. Roger, got it. I’m not concerned with those. Some very serious people have seen and recorded things that cannot be explained by anything we have any knowledge about that operate seemingly intelligently in ways our understanding of physics cannot explain. Those are the objects I am interested in, not space rocks that occasionally visit us.
In a universe that is boundless beyond scientific comprehension, it would be extremely arrogant of us to assume that we are the only form of intelligent life.
Also, many (such as the "Navy tapes") get explained as ordinary physics that results from existing sensing technology. Beyond that, our stupendous military budget is hard at work making super fast weapons and technology for confounding military grade sensing technology of the US and other countries. For clear reasons, the military isn't going to give us the good stuff. Civilians are always going to be behind the curve. I think what this means is that there is a high bar for evidence of ETs.
I know, right? Thank goodness for Chuck Schumer! But Republicans in the House poison-pilled the latest Defense Act with abortion ban stuff. Everything hangs in the balance!
