Aliens.

Okey.

So, our highly complex human minds aren't developed to the extent to percieve and accept certian things.

For instance, there's no proof what lies beyond our galaxy, as our minds and bodies are not capable of going there, barely to leave our planet, as we aren't progammed, designed to defy gravitational force. We can't design a bubble that a person can enter and survive to travel the cosmic realm.

There are gates that we travel through. Most people fill their spirit, sub- and consciousness by focussing on past, present and future which leave them unable to experience travels through these portals. Focus on things beyond time, beyond the now, beyond self, beyond others, beyond the countless shit you gather day in and day out to make the life for past, present and future easier to accept, so to say.

Better yet, focus on a void, an immense space, nothing. That void which you strive to fill with light.

Let go.
