Other things that make me wonder are tools and fasteners (nails, screws) comparable to modern ones have been unearthed in seams of coal far underground.
Once upon a time I was talking to a gentleman who'd done quite a bit of tunneling work.
One story he told was finding archeological evidence far inside a mountain about 4500' under the peak.
And like many construction companies, they kept quiet and kept digging.
Using our modern day calendar, when did the 3rd cycle start?

It hard to imagine aliens a million years more advanced then us. Mind boggling to think what we humans could do in a few billion years if we survive that long.

Throughout history, there has been catastrohic events (i.e. ice ages, extinction, etc.). Could it be possible that with the 4.5 billion year old planet (oldest rocks on Earth date to around that time) we are living on it could have had at one time ancient civilizations, ones that had a superior intelligence like or even greater than our own?
I've given this a lot of thought and it seems that because of the age of the Earth there could possibly have been great civilizations much like our own. Humans or human like peoples could have populated the Earth but because of the amount of time and the events that Earth has succumed to, we are unable to find any evidence of these people.
Even with Evolution, this theory I think could still work. Imagine if you will a terrible catastrophy like Nuclear Winter, many people are killed by the devastation, leaving only a few that move into caves, possibly even de-evolving...
