Alien Tomb Found In Tayos Caves?

The enigmatic story of a underground "man made cave" dated before the ice age has always been one the most incredible stories of Ancient Astronauts Theory. The cave is in the middle of the Amazon, and apparently what was found inside, would change history for ever. Apparently inside the cave was found an ancient metallic library, what was interesting about this library was the writing on it. It was Sumerian, but the cave was in the middle of a South American Country name Ecuador. Could this cave be the proof of a advance race living on Earth before us? The inside of the cave is really impressive, flat polished walls, flat ceilings and massive chambers that could be the home of some Intraterrestriall beings.
