No.

God is. We don't get to define Him.
God is NOT to each person what they make of it. That's insane reasoning!
We can try to ignore God but it doesn't really matter what theories we propose.
They don't change reality.
And a thousand human fabricated concepts don't put a tiny dent in the Truth.

Eternity exists.
Where you spend it matters.
So what you choose to believe in this short life matters incredibly for all eternity.

Please don't let people tell you that your own ideas have any ability to effect reality.
Different wishes about a brick wall won't change what happens if you drive into one at 100 kph.
And they won't change what happens when you die either.
That's determined by a simple test: either you want to know the real God, or you don't.
