I don't see how us not having build a technological civilization earlier in our history does constitute evidence that we only have the minimum intelligence that is necessary to do so. I don't think that intelligence makes as much of a difference to how quickly discoveries are made as you seem to think.

I have never seen you explain the concept nor have I seen you refer to an explanation. I must have missed that, but I also haven't read all of your comments.
