“Science makes many presumptions to arrive at an age of 13.8 billion years for the universe.”
You mean assumptions and you are wrong about that.
“Such as, science assumes the speed of light is 186K miles a sec”
That’s not an assumption, dickbag, that’s the conclusion of a great deal of testing.
“AND this has always has been a constant.”
Well, we have no evidence that it’s ever not been a constant. If you want it to be different, you need to provide actual evidence that it was, or even that it could be.
“But Genesis infers”
No. YOU infer from what Genesis says, by adding scientific knowledge you have that the the authors of Genesis did not.
“that initially light was infinite in speed and illuminated the universe without stars.”
Yeah, that’s how we know it’s a fairy tale.
“God lowered the original speed of light so we could see stars at night that He made.”
You’re not supposed to add to the narrative. Bible says that in several places.
“Secondly, science ignores all anomalies that contradict adverse issues. Such as, if the Earth were as old as you say like 4.6 billion years , then the oceans would be much more salty than they are.”
Does science ignore it or did the idiot who came up with this claim never talk to any oceans expert?
“The inverse of the current rate of change in salinity places the age of the oceans at around 10,000 years.”
So, wait, it’s bad to assume that the speed of light is constant, but you’re cool with assuming that the rate of salinity change is steady through all time?
What a hypocrite.
“The same is true for nickel powder from meteorites being deposited only on the outer edges of the Earth surface. If the Earth were billions of years old, you would find evidence of nickel at a much greater depth. But you don't.”
Have you asked a Geologist about this? They might know what’s going on, there.
“I believe science that depends on truth, facts, and all data not just excluding evidence that conflicts with non-science suppositions.”
No.
You believe in the Bible, and work backwards to accepting those part of science you can shoehorn into your superstition.
