I think there's things that exist that only God knows about. Science will never discover these, since they are not on this earth. I believe there are other worlds besides this world but only God knows is aware of them. We can only read about them in scriptures.
“Verily I say, the creation of God embraceth worlds besides this world, and creatures apart from these creatures. In each of these worlds He hath ordained things which none can search except Himself, the All-Searching, the All-Wise.” Gleanings, pp. 152-153
“As to thy question concerning the worlds of God. Know thou of a truth that the worlds of God are countless in their number, and infinite in their range. None can reckon or comprehend them except God, the All-Knowing, the All-Wise.” Gleanings, pp. 151-152
There are also human spirits and non-human entities in this world that only psychic mediums can perceive, see, and hear. I also believe that there are strange creatures (known as cryptids) in this world that are rarely seen and photographed. As a medium, I'm aware of paranormal events that cannot be proven by ghost-hunting equipment, explained by science, or legitimately explained away by religious dogma that strongly opposes the idea that the spirits of the dead can talk to and interact with the living. I'm well aware that there are supernatural events that defy scientific or religious explanation.
