The tip of the pyramidberg?
In the grand sweep of things, it is possible to theorize that life on Mars existed at one point, even without "documentation" or "proof" or "artifacts." This, sans any allegations of that-which-is-called conspiracy theory.
It is easy to pooh-pooh such thinking, but in the grand sweep of things, it's possible.
My concern is that with all the chicanery involved in, for example, UFOlogy --like fake videos and photographs --that genuine evidence exists, yet will be ignored because of the pooh-poohers.
I haven't researched the orgin of this particular bit of so-called evidence, but I will not off-handedly dismiss the possibility that this is an actual artifact. Not saying it is, not saying it isn't, but I personally refuse to be hidebound by the dismissive attitude of "It can't be, so it isn't, and therefore let's make fun of it."
I will grant that is perfectly possible that this is a fraudulent attempt to provide "evidence" of Martians for whatever motivations lie behind it. But it is also possible, in the grand sweep of things, that this is an actual artifact of past civilizations on Mars.
Jes' sayin'.
