Is it ok to believe and god and jesus but not believe 100 percent in everything the bible says. [Spirituality & Religion]

Like i believe in god but some stuff in the bible sounds kind of far fetched. Like how true Christians believe the world is only 8000 years old, the first humans lived 100s of years, and if you dont believe in Christ and follow his teachings you burn in hell forever. I also believe that maybe reincarnation could be real,it makes sense to me. Does anyone feel like i do? Or if you're a hardcore Christian do you feel id burn in hell since i question those things in the bible, even if i still believe in god and jesus?
