Is my argument against afterlife an equivocation fallacy?

[arewethereyet]

Dante, following Thomas Aquinas and the general ideas of Neoplatonic philosophers, says that there is no time or space in heaven. It is not in the material world. 

The experience of heaven, according to those guys, is like a single instant of extreme bliss. But there would be no chronoperception because time would not be passing.

I think hardly anybody today believes that afterlife is real, but that Near Death Experiences are not glimpses of it. Sure, that's entirely possible (and arguably probable if we assume afterlife is real), but we should be trying to refute the form of religion most people believe (or at least claim to believe) in.

You don't think anyone believes in an afterlife?  That's pretty much the basis for Christianity.
