Even so, there are many true realities that exist beyond the physical.

Agreed.

Like ultra violet, all we need are the tools to verify them.

Not a good example. Invincible does not mean non physical.

This is easy to prove as the mind, the emotions, our imagination and our dreams are not a part of physical reality yet few would deny their existence.

Not part of physical reality, however it is created by physical activities.

Why would many perceive sensations beyond the physical while others do not

Do they really?

Polls show that the majority of people believe in God in some form and an afterlife. Why is this? It is largely because most people sense the existence within themselves of something that is connected to realities beyond the physical senses.

Nope. It is because we are self-aware and question everything including our own existence. God was not just perceived to explain existence but to explain also, uncontrollable events which caused men to fear their physical world. Natural disasters, draughts, etc... Not all Gods are invincible and non-physical. Some are statues, trees, the sun, the sea, thunder.

There lies within each one of us a connection with infinite Intelligence.

Possibly, but so far all I can think of is the information stored in our DNA.
