Some people estimate 70 million mummies, but I think that's an underestimate. Mummification was carried out in Egypt, as I mentioned, for over 3,000 years. I'm sure more human mummies were made during this time period. If you look at animal mummies, several hundred thousand mummies have been found even in one cemetery. Countless mummies have been destroyed by tomb raiders seeking treasures within their linen wrappings.
The only thing we really know with 100% certainty is that humans have been taking DMT for several thousand years. In 1990, two mummified human bodies were dug up near the Matanza River in northwestern Argentina. The mummies were very well preserved, both being adorned with high quality woolen mantles.
