If comets have been proven by all scientists alike to only be able to "survive" for roughly 100,000 years, how are any still around if the universe is 4.5 billion years old?
Where did this come from? This is bogus.
There are literally hundreds of comets around the Sun with orbital periods in multiple 100,000 years (for a single orbit!).
I don't want to hear about Star Trek type Oort Clouds either btw.
Is there something about objective reality that bothers you?
You may have some strange ideas in your head, Flyer, but you are a decent enough chap here. And you have been here long enough to know better than to spout something without having done at least a minimal knowledge search.

Continental uplifting does NOT occur in Egypt. If uplifting does not occur, sea shells should not be found in the desert. Subsidance occurs on almost all edges of most techtonic plates.
You do know that the area of earth we call Egypt was not always desert, don't you? Any idea how deep the water was over this area? Or how many times it was submerged, dried out and re-submerged?
And to be accurate, subsidence, in this case more accurately called subduction, occurs in almost half the cases. Care to guess what is happening to that part of the neighboring plate it is subducting under?
Subsidence usually refers to an area of crust losing elevation because the underlaying structure cannot support the crust or because a lot of new material has been added like in an ice age.
Except you don't believe in Ice Ages, do you? I mean the evidence we have shows the last one occurred some 25,000 years ago, well before the earth was even formed, right?
