If the flood was not world wide then not all life would have perished. I think it's clear that the Bible states that the flood took all lives.
It says all life on the "land" that was flooded. Not all life in the world.
1. Oil and gas under pressure. It surely should have escaped if the earth is as old as claimed,
Most of it did. Only where it happened to be under impermiable formations like salt domes, did it stay underground for more than a few million years. And yes, there are places where it came to the surface and pooled.
The moon is slowly moving away from the earth. It should be loose in space, not orbiting by now.
The moon is not as old as the Earth. Evidence shows it was formed by a collision of the Earth with a Mars-sized object. And fossilized tidal rhythmites show how the distance changed over time. Pretty much what physics predicts. You see, it's moving outward because it gains energy from the Earth (thus very slightly slowing the Earth) by tidal forces on coastlines. The rate has changed over the ages, because of differences in the amount of coastline. But the math shows that the rate is consistent with fossil evidence.
No one knows if the speed of light has been constant throughout time
The speed of light is a factor in radioactive decay. It it had been significantly greater in the Earth's time, the increased amount of ionizing radiation would have fried all living things, and left evidence in the rocks. So that doesn't work.
There is vastly less matter than suggested by a 13 billion year old universe
7. Dark matter/energy has not been found. The likely reason is that it does not exist.
8. Matter and anti matter were supposedly produced by the "Big Bang". They should have neutralised each other to produce the big non event.
None of these have anything to do with the age of the Earth.
No, that's wrong. Evolutionary theory assumes life began somehow, and describes how it changes over time. So exactly how it began is not an issue. However, scientists working on that subject are coming to believe that the Earth produced living things, which is what God said.
I have to disagree on that point also.
God says:
Genesis 1:24 And God said: Let the earth bring forth the living creature in its kind, cattle and creeping things, and beasts of the earth, according to their kinds. And it was so done.
There is no implication that God sprinkled Evo dust on the water and wandered off to get on with something else.
God used nature He had already created to do much of creation. He's still completely involved with every particle of this universe. He doesn't have to tinker with it to make it work, though. Again, the creation of life has nothing to do with evolutionary theory. Even if God had just magically poofed the first living things into being, it wouldn't matter to evolutionary theory.
I'm sorry to hear of your friend's illness. He will be in my prayers. I think the anger we sometimes see in these discussions is unfortunate. YE creationists are no less Christians than any other Christian, and we should always remember that this issue is not one that will affect our salvation.
If you want to continue this later, I'm fine with that. Take care.
