I believe in UFO's... as in people see flying objects the are unidentified.

As far as the pyramids and hundreds if not thousands of other ancient structures I feel it is a gross disservice to humankind and our ingenuity to think that we needed help from extraterrestrials to build them. I have watched documentaries where they figured out how to build a pyramid.

And yes space is really, really big and there are a lot of planets out there however our earth won the cosmic lottery. Molten metallic core that puts out a magnetic field that deflects the suns radiation and keeps us all from being microwaved. A few miles closer to the sun and too hot for life... a few miles farther away and too cold for life. The perfect balance of chemicals, elements, water...

Plus as others have stated if there is any life out there it would take hundreds of years to get to them (or they to us).
