Energy

Everything has the energy of life within it, from the air, to the plants, people, animals, and other living things, to the rocks and the things within the Earth as well.

How could you not believe that there are energies present in and resonating throughout everything in our world, when there is proof?

Quartz Crystal is a great example. Its properties enable it to provide accurate measurement of time in clocks, through its resonant frequency.

People who are able to perform dowsing (aka "water witching") of water, metals, ores, gemstones, etc. are another great example. They are in tune with these energies, either consciously or through having an open mind and allowing it to subconsciously happen.

Finding a way to tap into these energies... now that's a whole other thing.
