Why does something exist ? How did it happen ?? and has it a reason ???

to get a answer on that we have to go to the Absolute beginning
before there was time and space, energy and matter.

First of all.. The First rule of physics..
energy can't be created or destroyed.. ( it only can transform )

If energy not can be created then it always was..
so every thing exist did and will always exist it only can transform like a puzzle

How do we know that.. because Energy is all and the first
nothing can be before energy because that is made of energy to

That is clear i hope..

With knowing the first rule u can answer all 3 questions
Why exist? because it is.. How happen? it always was.. reason? No !

if it had a reason that means some one or something give it a reason
and that is in conflict with the first rule

the same thing with God.. God is not the creator of all That is Energy
example: Energy can create a God but God cant create Energy
Btw.. its funny when u rename God to Energy then u get a whole new picture of God
God/Energy= Warm
God/Energy= Light
God/Energy= Everything
God/Energy= Almighty
God/Energy= The Creator
God/Energy= 4 Ever

When u ask me do i believe in God i would say No!!
not in that God as we have learned
But if u mean with God Energy my answer will still be No!!
i dont believe in energy i know it exist
u can only believe things u dont know...
