I'm quite satisfied that there is life elsewhere in the vastness of the universe, including many variations of what we would consider intelligent life. However, the vast distances and the limitations imposed by the laws of physics prevents interstellar travel. We have never been visited because anyone intelligent enough to consider it, would also know that it is impossible.

You're making a huge assumption-that we know all there is to know about physics.

I think 10,000 years from now, we might very well have discovered a way to travel interstellar distances quickly

Why couldn't other, much older, civilizations have already made the same discovery?I'm not saying I'm convinced ETs have visited the earth, I'm just saying that it is in the realm of possibility

But do us human beings know everything there is to know about physics and interstellar travel?
