Meh. I'm just taking it at face value. If 100 people came up to me and said they saw a UFO land in the field last night, I would definitely believe they saw something, and I would probably be more inclined to believe that aliens are visiting our planet.
There are literally billions of people telling me that a god of some sort exists. This is something which makes me more inclined to believe a god exists. However, there are many other things which offset that inclination.
I live but a few miles from Loch Ness. Thousands (millions?) believe in the monster, hundreds of people have seen the monster, lots have even filmed the monster. Many of these witnesses are of sound mind and good character. The monster, on the other hand, does not exist.
