Yes, I am sure, and I think that God doesn't exist because he can't exist in more than 1 time-frame.
In the bible, Jesus was born at around 5 ± 1 B.C.(E.) and was interpreted as a god and his people's saviour from Satan and stuff, but then again he apparently created the Universe with his bare hands and mind in just 6 days! In the bible that was 5000-6000 years PRIOR to his birth, though the universe was actually created ~13.8 BILLION years ago.
Jesus can also walk on water, bring the dead to life, turn water to wine, distort the atoms around him to make something completely different (ie, turning dirt from the ground into humans, which is (on a molecular level) converting Silicon, Calcium, Carbonates, and Oxygen and turning it into water, Carbon, Hydrogen, and Nitrogen (without even blowing them up or causing a nuclear cataclysm from rearranging atoms in ways that are literally impossible to do!))
There are many other things that he has done that defy science, but I won't get into them because it would take some time to explain tbh... :/
