This is completely false. we could build exact replicas of any ancient monument with ease and much quicker than ancient man did. The only issue is getting someone to pay for it
Do not belittle our ancestors by suggesting they were not able to construct these monuments on their own just because YOU can't.

Ancient aliens has no more credibility than creationism.
