I certainly believe there are other planets with life on them, some maybe intelligent. There are just too many star in the billions of galaxies out there for there not to be.

But space is vast. Even if intelligent aliens had life spans last lasted thousands of year, or even if aliens had conquered death, or never new dying of old age, the distance between the stars is not easily traversed.

Could aliens visit us? Sure. Have they? I don’t think so.

If advanced aliens want us to know about them, we will. If they don’t, we won’t. Their technology and intelligence would be able to keep them hidden if they wished it. If they want us to know about them, they would make it clear. There would be no guessing. There would be no accidental sightings.

And don’t even get me started on crop circles. Advance aliens travel thousands of light years with their incredible technology and all they do is make crop circles?
