Uh, no... you can simply add up the years in the bible to get about 4,000 years from Adam to Christ. In my figuring, the universe legitimately looks several billion years old. Then again, Adam has always been conceived of as having been formed an adult. Why would Adam be formed mature, why do scientists expect that the universe would not have been formed mature? And why do creationists expect that the universe should not look old?
Adam was 933 years old when he died; that’s 933 years from the time he was cast out of the Garden, not from the time he was created.
He was created a ***spiritual*** ***immortal*** being. For all we know he could have existed billions of years as a spiritual immortal being, inside the Garden.
Time is not a physical phenomenon. Physicists do not recognize time as anything physical; it is a linear measure that transitions to a nonlinear measure in the presence of singularities such as Black Holes, but it is just a measure that is used in the definition of mechanical parameters such as velocity, acceleration, power etc.
Time grinds to a halt when a body approaches the speed of light.
God is infinite, God is light. Time has no attachment to God; He is infinite, without bound.
