thats just typical of scientists. they think they know the answer to everything when in fact they no nothing. the reason they won't do the research themselfs is because they know they will find them to be manmade and that idea just won't work in their tiny little minds so they outright dismiss it as usual. we need to force these scientists back to reality they have been stuck in the dark ages too long. and obviously will have to rewrite history as these manmade structures are manmade.
