Be patience, he did use the cup of water and handful of sand to comprehend sedimentary layers. No bible taught him that.
Maybe his inspirations are crossing up. Unknowingly he is observing science to write these posts beyond religious opinion. Eventually the learning curve will set in.
The Bible predicted in
Daniel 12 that knowledge shall be increased, and this includes scientific knowledge.
Now note that Gentry got the idea that it proved the instantaneous creation of the earth from the Bible.
See Psalm 33:9.
And Gentry also got the idea that it proved the flood from the flood description in
Gen 6-8.
Also Gentry figured out that the 10 commandments were written on stone and probably granite.
The 4th commandment says that God created all things in 6 days, so Gentry noted that the Earth was created on day 1.
See Exodus 20:10 and Genesis .
So amazingly, God wrote the 10 commandments including the 4th commandment on granite instantaneously created when the Earth was created with very many parentless polonium radio haloes in the granite which proves 6 day creation about 6000 years ago And refutes evolution and billions of years.
Robert Gentry showed that parentless polonium 210, 214, and 218 radio haloes must be primordial based on the decay rates of the isotopes in the decay chain.
And he gave a simple falsification test that has yet been met. This test should be child’s play today. Not only can they not produce the granite with even one polonium 218 halo, they can’t even make that type of granite with the coarse grain.
How do you explain that?
Also he showed, using some polonium halos which are not primordial, that the rock layers are from the flood and laid down within a period of about 1 year.
If Gentry’s reasoning is correct, he has found direct evidence for the instantaneous creation of the Earth and of the worldwide flood.
There are many trillions and trillions of these halos in granite rocks all around the world.
I guess you have not read his book?
If you do you would know that Gentry faced a lot of censorship in many forms.
