Phenomena & Unexplained documentaries

On a late summer evening in 1977, Ohio radio astronomers discovered a strong, interstellar signal that is believed by many to be the best evidence of communication from an extraterrestrial civilization.

Around the turn of the 19th century, there were hundreds of reports from reputable sources of giant skeletons unearthed from ancient burial mounds across America. Human giants may not be entirely a product of legend in our history. Giants are spoken of persistently in the Bible and North American folklore - David and Goliath, Jack and the Beanstalk, and Paul Bunyon are familiar examples of tales involving giants. Has proof of Giants in our past already been found and is being suppressed by our modern culture who can't handle the truth as it would conflict with the academic world? These magnificent people were either humans like us, just larger... or were an ancient people that pre-dated our modern civilization and could have been their own species, possibly alien which would explain the reason behind the suppression of proof.
