I'm with Mulder on this, as in, I want to believe. But afik all of the examples in AAS's list have been more or less convincingly explained without recourse to ancient aliens.

Some instances (Baijong pipes for example) can be explained as the product of natural processes that just have an oddly artificial appearance to them. Others can be explained by our increasing knowledge of how advanced some old civilisations actually were, compared to our previous views of them.

To respond to a point, I think a lot of these extra-terrestrial explanations are rooted in a modern belief that ancient peoples were barely capable of rubbing two sticks together, thus anything a bit clever like electro-plating or accurate astronomy must necessarily be due to alien interventions. I can believe that you personally don't think that AAS, but some people do. Conversely I think I can be skeptical about the AAT evidence so far, without arrogantly believing that life exists only on Earth.

The alien DNA thing ... I'm none too well read on that but I don't quite get the comment in your post AAS - afik the genes in question are present in all life on Earth, just more prevalent in human DNA. I don't know what it is about these strands that have caused them to be labelled 'alien', but personally I find panspermia to be as likely an explanation of life on Earth as any, especially with modern discoveries of extremophiles and creatures like the tardibear.

Latest news on the Curiosity discoveries is that the evidence is still inconclusive. But even if it turns out to be the case that organic compunds indigenous to Mars have been found (as opposed to contamination from investigation I mean - n.b. panspermia), it's a heck of a long way from that to advanced races intervening in Earth's history.

Given the size of the known universe, it is almost certain that list exists somewhere out there on another planet. For the Earth to be the only planet in the entire universe, the chances of life arising around any given star would have to be something of the order of 0.00000000000000000001429%.

But whether that life has ever visited Earth or not is another question entirely.

Is that connected to the the Drake equation or something entirely different?

I agree anyway, the possiblity of ET life is completely separate from the question of ET visitors here now or at any other time. It isn't just the mind-boggling spacial distances involved, but also the immense distances in time - nearby ET civilisations could have risen and fallen while we were just a spark in some protein's eye, and equally could arise long after we are dust.

No - it's based on an estimate of the number of stars in the universe, 7 x 10^22.

Haha no . Due to the nature of what you say, anything and everything you say needs to be sourced .

Again from an admittedly uninformed point of view, but it seems to me that without a definite answer on how life actually began on this planet or elsewhere, it's problematic to assess the odds.

Although it's a rough and ready estimate, and assumes equal odds of life arising around any given star (which is not the case, but let's assume an average), the rationale is fairly simple. If the given figure is the odds of life arising around a particular star, then given the number of stars in the universe, there will be at least one star in the entire universe with life. That's not to say that there won't be more than one, but the probability is low.

The point of the figure is to illustrate how astronomically rare life would have to be in order for our planet to be the only one in the entire Universe with life - or even just life as we know it, Jim.

It's all due to time travelling ninjas. I've said this before. Why won't anyone believe me?

Yes I get the rationale ... my point was that we don't know how astronomically unlikely the circumstances were which led to life. I'll ask the ninjas next time they visit my space-time.
