Of course, we realize your question and that you're not slamming anyone's faith ... however, each individual can only answer in their own context. How can I say what people would do? Because I have an innate sense of the Unity between Human Beings and that Power/Light some refer to as God, it is impossible for me to "imagine" anything else ...
If the only reason Human Beings were created is to realize God, what else is there to do? There would not be Human Beings if God did not exist. We are a part of Him, the Soul is a Ray of Light eminating from His Light/Sun.
Not all people have an awareness of the Power that is God; hence the terrible things that are happening in the world. People believe in a religion, a path, a form. God has no religion, no path, no form. Ever wonder what the "dark matter" (which is an ironic name but not accurate methinks - "mystery matter" would be a more valid name) that was recently discovered in the Universe is? That "thing" or power that is holding the entire universe together ... that power that cannot be captured or contained within any concept; That perhaps hints at the Beyond that few want to explore.
Purple, you're attempting to elicit a response that suits your question; however, people can only relate to that within their own knowledge. It is like saying "if one cannot taste the flavor of an orange because we're unaware of that taste, does the orange still have a flavor"? Or perhaps more notably, "if a tree falls in the forest when no one is there does it make a sound?" lol
Such is the paradigm of existence.
In seeking a response to your question, you are seemingly expecting us to answer in the context you created; it can't be done. You yourself will need to answer your own question in order for it to suit your own inquiry. Again, such is the paradigm.
A possible place to explore is the film "What the Bleep Do We Know!?" which mixes belief in a higher Power and quantum physics. I highly recommend it to anyone curious about life.
How far down the rabbit hole are you willing to go? ......
Peace
