LH,

"And that applies to "little green men" too."

1. They are reddish brown, not green.

2. They have as much ( no more OR less) right to be here as Chongo does.

3. The point is, if the POSSIBLE is to be considered, regardless of LIKELIHOOD, than the "aliens did it" is JUST as valid as the conspiracy theories with no proof. All most are asking for here is PROOF, not "it could have happeened, so that must be what happened."
What has been offered has been looked at, and found wanting, IMHO.

Can I PROVE that it was NOT a conspiracy? NO.
Can YOU PROVE that it was NOT aliens? Again, NO.

But both are in the highly unlikely catagory until SOME real evidence is presented.
