In today's technological development, the ancient Chinese thousands of years of ghosts and gods legends exist or not?

It's hard to say whether demons, ghosts and gods exist or not, just like aliens, aliens could be demons and ghosts, completely invisible. The reason why there are so many ghost stories, because the ancients lack of scientific knowledge fabricated self-congratulatory things, but we are not the ancients after all, in fact, there is no gods and ghosts are not known. Let's just think of ghosts and gods as the God of the West, Westerners believe that science is more thorough than the Chinese earlier, but they still pray to God every day to honor their loved ones and great people. Don't we Chinese also often go to temples to worship Buddha? Since there are so many people believe in science and religion, we might as well believe in the so-called conscience of heaven and earth, gods, ghosts and Buddha, and what's wrong with that.
