Actually I said, "The probablility that it was manmade is almost zero, and when you go back to the late 1940s and 50s, there is simply no way we had that kind of technology then ... so far as I know, we still don't."
Because I made no absolute statement, and instead used the words "probablity" and "almost zero" and "as far as I know", I can abosultely know that what I said is true based on my firsthand experience and the examination of available data on known manmade craft.

Good, wouldn't you agree then that the null hypothesis which is:
"All UFO sightings are of mundane origin"
hasn't been falsified in this thread?
