That's an interesting concept, my thoughts are that our true history has been hidden from us, we have clearly had lots of past civilizations whitewashed from our history, check out the recent Malta video from the newearth channel on YouTube
(there is also some evidence for past civilizations on the moon and mars as well),
does something like a large planet cause this? Interesting
I thought it was perhaps just the sun doing its thing going through its cycles, I at first dismissed the planet X stories, but your right something is affecting our sun, which causes it to have cycles.
I agree with the ancient civilization theories and such as well. I mean c'mon.. Atlantis and what not being in every ancient culture's myth book. And that our history is most certainly being hidden from us deliberately.. just look what garbage they teach our kids now in school.. yikes.
