Not that I beleive in this stuff, but for those who like to think about futuristic predictions, here is something.
The Prophecies of Nostradamus:
"A mile-wide mountain (asteroid) strikes earth
after there is peace, war, famine, and floods,
the asteroid strike causes widespread flooding of nations,
some of which are ancient.
Biblical prophecy in Revelation chapter 8, also indicates that in the "End Times" period dominated by the Antichrist, one or more
asteroids or pieces of a comet will strike earth, causing worldwide disaster. According to
this Bible Code matrix this could happen in year 2007. Compare to Revelation 8:8 (King James Version):
"And the second angel sounded,
and as it were a great mountain burning with fire was cast into the sea,
and the third part of the sea became blood."
Nostradamus predicted that the Anti-Christ would die off as an astroid strikes earth, that causes floods and war and famine.
Later on in Rev. it states the disposition of the Anti-christ. So yes some space object strikes earth, but it's function is to cause widespread devastation, not kill the anti-christ.
