Some points have benn well made that suggest it is highly unlikely we have been visited by sentient creatures from beyond our own planet. We know it is highly unlikely that such creatures exist within 1000s of light years from our planet. Would such creatures - even if capable of near light speed travel - spend thousands of years to travel to our speck in the galaxy only to buzz around in secrecy or capture specimens for a bit of alimentary surgery? Piffle. Could they do the infamous folding space trick to get here in next to no time? One problem - the simple laws of physics. (Don't think that morons with prepostorous ideas of defying physics are excluded from membership of the scientific community).

Of course, then there is the notion of time travel. Well, if such a ludicrous suggestion of being able, for example, to go back in time to predate your birth rings your bells, then consider the question of why there has never, at any point in history, been a credible report of interaction with someone from another time period. Think about it. For an infinite period beyond a certain point in time, some civilisation somewhere invents time travel. Therefore, there would be an indeterminate number of such creatures (whether man or extraterrestrial) that have visited/will visit us in the past. Again, piffle.

If you consider all of these outlandish suggestions in the cold light of reality and then extrapolate the implications from these theories, they simply cannot hold up. But as we know from other threads, some people just want to believe and genuinely appear to believe in their own eccentric postulations.

Bah, humbug.

One of the most eccentric postulations I do believe I've ever read.

Some people post in outside the box....from inside a box. A neat piece of self hypnosis.

Regards.

That's a little bit hard to swallow...and I think a dramatic exageration to say an atom in me was probably once in Ghandi and Hitler.....consider the number of atoms in me vs the number of atoms in the world.....a few of Jesus's atoms have a greater chance of being in me, in that they have had a greater time to disperse around the globe.....but still unlikely I would guess.

Nonetheless, it would be true to say that all my atoms originated somewhere out there.

The endosymbiotic theory does bring to mind the "cell memory" idea (as some organ donor recipients have attested to) and past life memories that some people claim.

Heard or read somewhere that every glass of water we drink has a good chance that a part of it came from the urine of earliest and subsequent life forms.

Don’t talk to aliens, warns Stephen Hawking

THE aliens are out there and Earth had better watch out, at least according to Stephen Hawking. He has suggested that extraterrestrials are almost certain to exist — but that instead of seeking them out, humanity should be doing all it that can to avoid any contact.

The suggestions come in a new documentary series in which Hawking, one of the world’s leading scientists, will set out his latest thinking on some of the universe’s greatest mysteries.

Alien life, he will suggest, is almost certain to exist in many other parts of the universe: not just in planets, but perhaps in the centre of stars or even floating in interplanetary space.

Hawking’s logic on aliens is, for him, unusually simple. The universe, he points out, has 100 billion galaxies, each containing hundreds of millions of stars. In such a big place, Earth is unlikely to be the only planet where life has evolved."

Stands to reason. Makes sense.

I can't wait to watch that doco.

Now I'm waiting for the lab reports on blood, urine and feces.

You left your underpants there?
