Life in outer space. It's the one I find easiest to comprehend the existence of.

Life after death.

Life in other dimensions, it's the only thing which seems uncertain or mysterious to me. Given the vastness of space (billions of billions of billions of stars), it is entirely reasonable to suggest that there are many 10's of thousands of other planets with life (Seriously, give the odds a million to one? that still leaves several hundred billion occurances of life. Give the chances 1 in a billion billion? That still leaves a billion occurances of life, etc : D) Also, since I think the question of life after death is technically unanswerable, I just look at what evidence we have: We are only alive and concious because of our brains, when we die our brains die, therefore we cease to conciously exist. But life in other dimensions... There is a lot of suggestion for the possibility of alternate dimensions (obviously nothing proven, just some interesting ideas which have varying degrees of evidence), so it is a question we are yet to answer properly, and currently don't have much insight into : )

Life after death

None of those..the mystery is just how many licks does it take to get to the center of a tootsie pop? :)

None of them. I think the biggest mystery is life before death. Just trying to figure out how to live the life we have in the best way possible.

Existence after biolife is for unbelievers. Life after biolife is for True Believers.Both occur in the spiritual dimension which is an other dimension.Man cant travel fast enough now in outer space to answer the question of life in outer space and it eventually dissapears anyway at the end of all things physcial.

So would the sixth sense qualify as a other dimension or life after death or both. I think the other dimension is pretty wild.

Life in other dimensions is a mind blower.

I think life after death is the most mysterious mystery. There has to be some kind of life form in outer space because the universe is so big and just because we can't see it, doesn't mean it's not out there. I don't know about life in other dimensions, but life after death puzzles me the most.

Since all three are essentially 'otherworldly' and beyond the scope of human comprehension, to me they are all equally 'mysterious'.

Life after Death.

I've been finding all three very intriguing for years... 1. Life after death - one of my best friends who passed away about a year ago has been visiting me in my dreams to explain how all of this works. Because the info comes to me in dreams, some of it I remember, some of it I don't. But basically, life after death IS life in other dimensions. However, before you can move on, you have to achieve a certain level of evolution here on earth. You will be reborn in this dimension several times over until you reach that level in which your soul is ready to move on. (If you are out on the internet - looking for answers to these types of questions - you'll be moving on.) 2. Life in other dimensions = life after earthly death; There are many dimensions and your soul will experience all of them. Scientists and mathmaticians are able to mathmatically show that there are many dimensions. I'm not even sure how many they are up to now. They are having problems with their "string theories" - because they're off track. 3. Life in outer space - yes there is. I find it amusing, ignorant and sometimes arrogant that some people think we're the only ones in the VAST universe and all of the galaxies out there. AND - as your soul moves on to other dimensions and transcends the space & time dimensions, you'll visit other galaxies throughout the universe. We're kind of "in training" here.

If I had to choose one, (which is quite difficult, because I find all three possibilities fascinating), I would say life after death, because that one is simply inevitable. It happens to everyone eventually. Great question +5

Life After Death, because it would have the most relevance to my life.
