PP is the evidence that some form of advanced technology existed in our ancient past.
No it is not. At best it is the evidence that some skill were lost,
it does not say whether the skills were high tech or low tech. But even that is wrong as there are indication that low tech skills were used, and that was provided to you more than once in this thread.
*YOU* have presented *NO* evidence of high tech. All you have presented is that you disbelieve the accepted hypotheses.
You are the same as a creationist saying that there is a problem with evolution, and then concluding "therefore creation".
NO ! Even if evolution was falsified, this is no evidence of creation !
One would have to provide independent evidence of creationism !
Your are doing exactly the same error :
AGAIN you have provided NO EVIDENCE of high tech. All you have provided is that you disbelieve the low tech hypotheses.
Even if the low evidence were shown to be poor, it does not prove the high tech hypotheses ! For that you would need MORE : you would need EVIDENCE OF HIGH TECH (independently of the poorness of the low tech evidence in your eye) !
ETA: If i showed you diamond, and I said you I fabricated those diamond in my life (*), and you disbelieved it, because of the weak evidence, and YOU said me I "bought" the diamond, you would have to provide evidence
I bought the diamond, because that is YOUR hypotheses, and tehre are many other explanation I could have found them, I could have stolen them, I could have gotten them as gift from my grandma. This is the problem here, it is not that you refuse the low tech explanation
it is that you provide an alternative explanation (high tech) and REFUSE to provide evidence.
