See e.g. this youtube vid:

Leaving aside all the stuff that perhaps isn't amenable to proof, and/or is outside the scope of this forum (e.g. suggestions that certain things are astrological allegories - like Christian fish symbol coming from Pisces, the number 12 in 12 disciples comes from 12 zodiac signs, and so forth) how accurate are the claims that so many features/aspects of Judeo-Christian religion have close parallels and similarities with e.g. the ancient Egyptian cult of Horus?
It's a relatively long vid with lots of claims, so please feel free to comment on the bits that interest you. Thanks.
Jesus and Horus is a pretty common conspiracy theory, generally based on a poor understanding of actual myths about Horus. I'm not an expert on Horus, so I'll just point you to some previous threads about this: https://www.reddit.com/r/AskHistorians/comments/15tpqk/is_this_claim_have_any_truth_horus_jesus/ https://www.reddit.com/r/AskHistorians/comments/2m9ccg/comparison_making_the_rounds_jesus_vs_horus/ https://www.reddit.com/r/AskHistorians/comments/2b7x00/the_jesus_myth_someone_care_to_explain/
