OK David, we've been here before.
Obviously we've found a sore spot with you.

Things that merit investigation with conclusions being applied to reasoning, are worthy of looking into. To be interested in the scientific investigations of an unusual set of circumstances (some of which have yielded the heavy hand of well-funded hoaxers with governmnet ties), is only normal for many individuals.
Those who look at evidence and then throw it away and consider those who look at it as "fools", are surely fools themselves.

What feelings do you get when you see the "bent nodes", the "exploded cell walls", the "twisted seed heads", the meteoritic magnetites,..............does it make you shudder?
Does your brain have trouble even wrapping around the concept that this IS happening?
And how does that make you feel?

Doesn't exactly fit into your view of the world?
Well, as a mathematician, you should at least be wondering who's not making the ones on the ground, the "pristine ones" that end up near megalithic sites and try and correlate it to an ADVANCED MILITARY PROJECT, and then take it from there.

Your refusal to look at the evidence shows me two things.
1) You have bought into the original media bias about this phenomena and feel secure that if 95% of the population thinks it's poppycock, then it HAS to be.
2) You feel threatened at some subconscious level that something extraordianry may be happening, and you don't want to even LOOK at it, let alone DEAL with it.

Before you go smearing your biases all over this thread, please look at the telling photographs....THE EVIDENCE...... and answer me the rather simple questions.............HOW was that done?
When you come up with a real thoughtful response, instead of an ad-hoc "ebnelson" flame, then I might consider you a participant in this thread.
Until then, please stop showing us your fear and your ignorance in capital letters.
