Why is the supernatural so hard to find in the modern-day? Is there a conspiracy to keep it hidden? Why would a group do such a thing? Why do Atheists exist?

While there is a lot of compelling evidence for the supernatural for many people, that leads to the question of why the supernatural is so hard to find. Shouldn't you run into it on a daily basis if there is no reason not to? Especially with how many supernatural entities are in Hinduism.
