For all anyone knows, this could be true. Stop assuming to know everything, that's the beauty of being human. We're always learning. Think of how far we'd be if everyone was open minded to every possibility.

Holy crap why can't everyone just leave each other alone and watch the video? After all, what is YOUTUBE for? ITS NOT FOR SUCH STUPID DEBATES BETWEEN PEOPLE SITTING AT HOME ON THEIR COMPUTERS... just watch the video... it's interesting... you might learn something...?

We went to the moon, but didn't explore it very thoroughly. Later we discovered there was ice in some of the craters. How could we not be curious enough to look for spores in that ice?

I would love to check for spores in the ice that is on the moon. Why are we going to Mars before we have explored the moon?

@mtbee9 I have the book "Evolution from Space" by Fred Hoyle and one of his Phd students at Cambridge, Chandra Wickramisignhe and without getting it out, I think they used the most simple cell that could be called "alive" to make the caculation 1 to 10 to the 40,000th power. But as the scientist here on this video says: "nobody knows how life began here on earth". Biologist Richard Dawkins said the same in his interview with Ben Stein. So I see you point. Numbers for an unknown event.

@boblackey1 "life as it exists on earth has a 1 in 10 to the 40,000th power chance to have formed"

I find it amusing that people can calculate the probability of something happening when they don't have all the facts. You have to know how life started before you can work out how likely it is to happen. It could easily be a natural occurrence when the chemical conditions are right. People have calculated an astronomical figure for the probability of god too. Means nothing.

@mtbee9 Life existing on a cosmic scale is what Fred Hoyle and his Phd student Chandra Wickramisinghe wrote in their book "Evolution From Space". I have no idea if that's right. Hoyle and Wickramisinghe caculated that life as it exists on earth has a 1 in 10 to the 40,000th power chance to have formed by chance which is a number they said is "larger than the number of atoms in the universe". So to them, life could not have developed by chance here on earth. No one knows how life began!!!

@boblackey1 " life exists on a cosmic scale". While I can agree that this is a possibility it is also very feasible that when the conditions for life to start are favorable then life will begin, just like any chemical reaction. Once a self replicating organism exists then evolution comes into play as to how it develops from a simple chemical form to more organized cells, etc.

@mtbee9 Frances Crick (co-discoverer of DNA) thought the rocket idea might be the answer for how life got here on earth. But Fred Hoyle rejected that, said it was too slow and small. To Hoyle life exists on a cosmic scale and probably arrived on earth via comets and space rocks. Indeed Hoyle and one of his Phd students at Cambridge (Wickramisinghe) did a paper claiming interstellar dust is made of bacteria. Most scientists reject that but N.C. Wickramisinghe, Phd still holds the position.

@boblackey1 "Life may not have had an origin." Interesting idea but if that were true how does life spread across the universe. If we assume that life started here there would have to be a mechanism for it to travel across space.

You could not rely on evolution to produce beings to create rockets and send of their 'seed' into space. It has been suggested that life can survive in microscopic form in the vacuum of space in which case it could be a  possible solution.

@mtbee9 Life may not have had an origin. It's possible, but to me not likely, that life has just always existed as has the uinverse. Sir Fred Hoyle, who was a big of an odd ball but a very smart scientist, leaned toward that view. Hoyle named the Big Bang who never believed the uinverse once didn't exist. As you know, the big bang actually says that matter, energy, time and space (yes space..no place for something to be located) didn't exist before 14.5 billion years ago.
