Anything but God!
Call it alternate dimensions, multiverse, whatever, and it's classified as *science*.
Call it *heaven*, *hell*, *the new heavens and the new earth* and see what kind of pejoratives it will earn you.
So many so-called *scientists* reject what is found in Scripture, then turn around and propose their own God free scenarios that have them end up in the same place. They're merely replacing the same things with one that doesn't require God and accountability.
