Geology, Geography, Physics, History, Paleontology, Biology, Cosmology, Astronomy, Chemistry, Botany, Archaeology and Anthropology all Conflict with Genesis. Even Leonardo da Vinci in the 15th century realized that Genesis was wrong and derided Genesis believers.
Genesis believers haven't changed since the 15th century, they are still among the dumbest people on the planet.
The problem with Genesis and the theory of relativity is that the theory of relativity is based on the fact that the big bang took place. Genisis is simply ancient mythology and the belief in it will hopefully continue to fade. They conflict because one is myth and one is absolute fact.
The theory of relativity does not conflict with Genesis. The are two totally different subjects that really do not relate in any way, shape or form. If you try hard enough, you can make anything conflict with something else, but on a base level, these two do on conflict each other.
The theory of relativity no more conflicts with Genesis than
a professional wrestler would fight with a boxer. These are two entirely
different ways of conceptualizing the world. One view is based on faith and
belief, the other on science and proof. The religious concepts that underlie
the book of Genesis cannot be scientifically proved, any more than a scientist can
take evolution on faith. Yet each discipline can respect the other’s way of
searching for the truth.
The theory of relativity does not conflict with Genesis. The Bible states how the world was created. We do not always recognize how God works or why He does what He does. Everything is not meant to have a complete matching explanation. Anyone who is religious will understand this rule.
I do not believe the theories of relativity conflict with Genesis. I believe one should read Genesis as though it is a story being told to a very young child. It is not based in scientific principal and shouldn't be considered straight fact. It should be considered a loose telling with the main goal of getting a common idea across.
