"A complete lack of any physical evidence" ACTUALLY means nothing, zero, zip, zilch...
Actually, in this case it doesn't. If you read what you just quoted:
"However, as noted by Kolata[4] subsequent archaeological research[6][7], has found a complete lack of any physical evidence, including prehistoric tools and dated midden deposits, for any occupation of the Tiwanaku site as old as argued by Posnansky
It doesn't say there is a complete lack of physical evidence, it says that there is a complete lack of physical evidence of a certain age. That implies that there is actually plenty of physical evidence that just happens to be more recent. Far from suggesting that all the tools evidence magically disappeared, it simply suggests that it may be a more recent construction than previously thought.
Without evidence you don't/can't know who built it.
And since we can't prove exactly who built it, it must have been a bunch of aliens for whom there is no evidence anywhere at all, who live on the bottom of the sea in a highly advanced technological society but decided to head to South America for a holiday to bang some rocks together. Do you really not realise just how insane that sounds? Your claims about Inca ruins don't even support the idea of your submarine aliens who can magically erase all evidence of their existence, since these ruins are neither submarine or erased.
But i'm also sad no one has given arguments against my list of indirect evidences for a foreign intelligence
Because you haven't given any. You've provided evidence of UFOs, but since no-one argues that they don't exist that's really not that impressive. Nothing you have said suggests any kind of intelligence, so there's really nothing to address.
