My understanding is that time is not linear in the way we think. A 25 thousand year cycle of incarnations could be spread over hundred of millions of years in linear time. Like the time of Atlantis within this cycle could have been millions of years in the past in linear time, but only 10 thousand years ago in terms of the cycle of incarnations. As if a big gap of linear time, where no incarnations was occurring on this planet, had lasted long enough to erase traces of the past and continue the cycle with a fresh start.
EDIT: Also, this 3d illusion we are in is setup to basically force us to develop faith. I have personal proof that reality is more that just material, yet it is not shareable. I could talk about the proof I have, but any listener would still need to take it on faith, so it's useless as a proof to others. This proof became available to me only after I had already accepted it on faith alone. So a proof was not needed at that point and yet this is when I got a proof cleverly setup so that I can't share it.
Anyway, it's good that you question the material like this. Because, only your own intuition can inform you of what is currently useful to you. If these doubts on parts of the Ra material were to result in you rejecting the whole thing, then so be it. It would just mean that this stuff is not what you need at this time. Maybe you could find it useful again in the future, we never know. At least you will be aware that this information is available.
Personally, there are things that I do not resonate with in the Ra material and I just ignore those parts. That does not bother me much. I figure that this is just another test of faith where the Law of Confusion comes into play.
