Re: Ancient Universe
Scientists knew the Earth was far older than 6,000 years in the early 1700's. The first recorded attempt to measure the age scientifically was in 1748, based on changes in sea level, and the result was "greater than 2 billion". Many methods were used over the next 150 years or so before the discovery of radioactivity, and the results varied extremely widely, but all the results were much more than 6,000 years.

Re: Ancient Universe
The earliest attempt to prove the age being longer that a few thousand year is a science fiction story written by De Maillet.
Which no one of the 1740's would have considered anything but science fiction. ...
De Maillet's science fiction book would have been accepted as presetnted. Fiction.
Buffon's caculations showed promise of a way to date the earth.
These fellows probably got the same reaction to their beliefs and I do to mine. Are you out of your mind?
De mMillet's calculations were not presented as fiction.
The rest of what I've quoted iis unsupported assertion. Pleaae present evidence.

Re: Ancient Universe
Obviously you can't read.
Samizdat.
And you have no support for your other claims? Just stuff you made up?

Re: Goading
I made an attempt to explain why. You missed it.
