David,

You have no idea about my training or education, but I believe
you understand evolution to a certain extent although we might
disagree on some aspects.

We are being visited by creatures of unknown origin. You favor
ETH as an explanation and I don't. I think star travel is
impossible and "zero" evidence exists that it will ever be
possible. Some scientists believe it may happen in the future,
not one can tell you how it could be accomplished without
resorting to exotic theories. Since I don't believe any of
these, I've considered other possibilities. While there isn't
any hard evidence, except for the creature in the AA, there
isn't any scientific reason to reject the ancient hominid
civilization as being responsible for UFO.

I have no argument with any of this. Did you think I might?

Convergent evolution doesn't prove anything. I have suggested
that convergent evolution is an accepted scientific theory that
can account for the possibility that other hominid type
creatures could evolve.

That's correct; all ant eaters look the same and have the same
basic anatomical tools to extract ants from the environment,
even though they are from different species and even thought
those tools are designed in a different manner.

Convergence is not resemblance

There is considerable discussion about the savanna theory and
human evolution. But that's for another thread.

There are only a few monotreme fossils. They were a transition
species between reptiles and mammals and very (almost nothing)
is known about their evolutionary history. The land masses that
now form our continents were all one huge continent when
monotremes first appeared. If they had evolved on what is now
Antarctica, there would be no evidence of their presence.

Not if it were under miles of ice or one hunderd million years old.

If this civilization evolved in Antarctica, there would be no
evidence. If it evolved one-hundred million years ago, there
would be little evidence after fifty-thousand years.

We might not even know what we had, if we did have something
suspicious. Humans have gone from chimps to astronauts in less
than seven million years. We evolved in several different
environments, but it has been our tool making that allowed us to
succeed. I think tool making was also the niche that created the
ancient hominids. As long as they were bipedal at some point,
and adopted tool use, then the tool making would create the
hominid form and eventually lead to civilization. These hominids
could have been quite intelligent and made rapid progress and
may have gone about their business differently from us.

I agree but there are only a few monotremes fossils at all.
There isn't much of a fossil record for this period. We get a
general idea of what was happening but very little specific
information. But I'm not wedded to only monotreme, since there
might have been several different civilizations during this
period. I decided on a monotreme from examining the creature in
the AA and the features it displayed.

An educated guess is that they are under the ice in Antarctica.

You reason that aliens from other stars are visiting us. You
believe this because you believe the vast trove of evidence that
all points to the fact that we are being visited. You have zero
evidence that these crafts come from the stars. Not one
scientific bit of evidence, but you still support this bizarre
notion. You have theories which account for ETH, but nothing
substantial. And my read of the literature say that it's not
possible, not now, not ever. Yet you cling to this faith. I
don't get it.

No, not necessarily. They have left their vehicles and a few of
their fellow creatures. And they have been known to other humans
for all of recorded history, but not as neighbors.
