Science is inherently atheistic

[Angrboda]

You can attempt to study vampires, but it's not scientific study. I'm not knocking you for believing it's possible, but it's not a very credible endeavor.

Science asks questions about the natural world

Science studies the natural world. This includes the components of the physical universe around us like atoms, plants, ecosystems, people, societies and galaxies, as well as the natural forces at work on those things. In contrast, science cannot study supernatural forces and explanations. For example, the idea that a supernatural afterlife exists is not a part of science since this afterlife operates outside the rules that govern the natural world.

Science makes no assumptions such as you are suggesting it does. That would be metaphysics, not science.
