That kind of story is way to common..reports of a crash..than the govt, military, nasa, men in black show up , clean up the site and the next day it is just a report of a weather balloon crash or some BS..

HAha seriously.
I can't exactly say what it was, but it definitely was not a small airplane crash that's for sure. I'm unbelieving that a 1 person airplane could shake the whole city. It scared the hell outta me when it hit, and I was still a couple miles away.

The odds of there being another planet able to support life as well as earth are just as improbably as there being a God....
To believe that it is not possible for there to be life elsewhere in the universe shows a total lack of understanding of the size of the universe and grand arrogance to suppose that humans are the only life in it -

as Carl Sagan said - If there is no other life out there - What an awful waste of SPACE!

Really? Do you know how many planets there are in the universe?
Astronomers estimate there are 1021 stars in the universe. With a conservative estimate of three planets per star (some could have many more, some would have none at all) this puts the estimated number of planets into millions of billions. The actual number of planets in the universe is difficult to ascertain. However we do know that the number is very very large. Think about it this way, as many grains of sand there are on earth cubed still wouldn't equal the correct number.

Our galaxy contains approximately 70 sextillion stars, though most lack planets. Current estimates say there are around 210 sextillion planets in the galaxy. There are about 100 billion galaxies in the observable universe. There are surely many galaxies outside the part of the universe we can observe and each contains a variable number of stars and average planets per star. Thus, currently we can say little more then 'probably more then 10 trillion'; that is, we can only guess at a lower limit.
When it comes to known planets in our galaxy, however, around 200 are known to exist.

How do we know WE arn't the aliens that were deposited here accidentally or otherwise by someone or some thing from another planet millions of years ago and evolved into what we are today.

I've read a lot of interesting research on this subject. Serious research, not UFO stuff. There's a growing amount of evidence that suggests that the first microbes on this planet may have been carried here on debris thrown up after a large asteroid impact with Mars. We may actually all be Martians.

Hogwash. There are billions of stars in our galaxy and billions of galaxies in the known universe. If only a small percentage of those stars have earth-like planets orbiting them then the probability of life on more than one of them is quite high. In fact, most serious astrophysicists agree that the chances are FAR slimmer that we're the only life in the universe than that the universe is teaming with life.

EDIT: Houdini just said the same thing... and far more articulately than I did.

Show me a single shred of evidence that these astronomers aren't pulling their numbers out of their you know whats.... everything they are claiming regarding the probability of ETs is based on.... nothing... there's no reference to base the chances of an earthlike planet occuring because there simply has never been a planet found to date that remotely resembles earth or can support life.

And the evidence that the probability of an earth-like planet among those billions of star systems even exists? There is none - astronomers and astrophyscists do not have a shred of evidence to backup their numbers.
