I don't know of anything specific to 500,000 years ago. A few people wanted me to re-post this topic on "UFO's in History".
About the "battery"... Who can prove that was a battery, or a paint mixer, or something else?
Anyway, there are some interesting paintings that clearly show UFO's in them. As far as I know, the most interesting paintings are real and their locations have been posted.
