You don't think our crucibles are up to the task of taking the heat to melt stone?
What do you mean by "stone"? Do you mean quartz? If so, sure. My little sister works with glass--got a degree in fine art in glass blowing. If you mean any other mineral, we do not have anything large enough to handle construction-sized stonework. And why bother? We'd have to cool it so fast that it would be glass. Not really useful.
Again, you are completely ignorant of basic geology (the definition of "rock" is given at the start of Geology 101 in every university I've ever encountered, and the whole melting point issue was dealt with during the "igneous rock" part).
In 'other' threads I have postulated that a LOOOOOONG time ago, one of our precursors could have ascended, and now exist as "E.T.'s"...the "gods of heaven", or whatever label you wish...EXCEPT 'aliens'. Given then they are from 'here', they are no more alien than we are.
We're not allowed to postulate that ancient humans used readily-available tools to carve simple shapes into rock, but you're allowed to postulate this sort of inanity? No. Provide evidence, at least. And I'm being generous here--if I played by your rules I'd say "Ascend or it never happened".
I never said THAT was the technique used...I was just spitballing.
No. You refuse to admit that we've provided multiple viable methods for producing the artifacts you're discussing because (and you are quite insistent on this point) we haven't done it. So either do it and provide evidence that whatever technique you're talking about is what did it, or it's not good enough. Or at least fess up to your double standard. Either way is fine by me.
'I' know what I know BECAUSE I have done some basic research, and have first hand knowledge of what carbide does to granite. I've also used HSS bits on marble, and cold forge steel chisels on limestone.
Bull. You haven't done the basic research necessary to KNOW WHAT YOU'RE TALKING ABOUT. Here I mean to know what rocks were used, how hard those rocks are, and what tools first graders know were lying around. What you've done is pound on some rocks with some tools. While useful, this is not sufficient research. Look at the archeological literature, look at what experiments have been done, in short step off your high horse and admit that other people TODAY aren't complete morons and maybe, just maybe, someone has asked a similar question, and then see if they have. It's fine to speculate and all, but to demand we accept your ideas when you consistently fail to demonstrate the most basic understanding of the systems involved is incredibly arrogant.
The OP here, merely asks are there "lost civilizations", which thus far, I think I've demonstrated there is...or are...
No. Thus far you've made assertions, backed them up with admittedly amateur attempts at experimentation, Argument from Ignorance (quite literally--we don't know how they did it, therefore the technology is lost; never mind the fact that several methods have been proposed), Argument from Personal Incredulity, and Argument from Ignoring Evidence. This is not sufficient evidence for supporting a theory which contradicts the whole of archeology. You need evidence AT LEAST of equal quality to a standard archeological argument. Preferably a lot better.
