Ancient Aliens is cram packed with false dilemmas, cherry picking, flawed reasoning. It is everything a documentary should not be. Quote from the series Pumapunka. 'While the pyramids at giza are an incredible achievement, compared to Pumapunka the pyramids are child's play This is stated by 'Giogio. T. Tsoukalos. He does this because he introduces two supposed facts. The stones are not sand stone or andesite but, granite and diorite. Diorite is the hardest stone on earth apart from diamond. Meaning the only way to cut or drill the stone is with diamond headed cutting tools. Therefore aliens did it. The issue is he created false dilemma, because the stones he chose are very hard and would be impossible for ancient man to manipulate. Problem is the blocks at Pumapunka are sandstone and diorite. He lied and it is something that is repeated in every episode. If a stone block weighs 130 tons ancient aliens adss seven hundred tons to make 800 ton blocks. Every episode is fantasy made up rubbish and rvry point ever made on ancient aliens the series is utterly false and wrong. You only need to google what are the stones made from at Pumapunka.
