Joe, are you building a theme here? You seem to have a fervent interest in the mysterious and unexplained. UFO's are something I've been interested in for forty years. I look at the subject this way. Space travel is an inevitable technological occurrance. A way of traversing inter-stellar distances is just a discovery away. Of course, for us that discovery may not show up for a few millenia. So why couldn't a species whose planet's lifeforms weren't wiped out not once but several times (like ours) be advanced enough to figure out true space travel? So why haven't aliens contacted us? I think because we're not ready yet. Look what we do to the planet and each other.
