Fabulous cave art from prehistoric times up to 50,000 years old and perhaps older would seem to push the thought that our ancient ancestors encountered alien beings!
Now, anyone who has read or experienced shamanic practices knows that it is not uncommon for these individuals (and others for that manner) to consume organics that are known to create ‘other worldly’ encounters… perhaps expriencing other dimensions that are unusual to our typical material world…
I have come to think that in these ancient bucolic cultures, it would have been a common practice to record these more remarkable and etheric encounters. Perhaps to help in sharing the experience with others, or to memorialize the event.
