No evidence suggests that there was an advanced civilization before us?

You don't think the pyramids being built on aquafers to use as powerhouses is advanced? How about the gigantic rocks all over the world at ancient sites, most of them older than the site as we know it, that even currently we would need gigantic cranes and earth moving machines to lift and move? What about the fact that so many ancient societies seem to have been aware of and have used celestial patterns? What about the fact that many pyramids and other monoliths are built directly on the earth's ley lines?

Also, the idea that we are aware of all of the laws of the universe is absolutely ridiculous.
