Everything is meaningless without God.
This is demonstrably false, as my life has meaning and purpose, and I have never believed in any gods.
It also is a argument from consequences fallacy, in that even if that were true, it would not poof your god into existence.
It also begs the question, have you the right god? Have you the right denomination? I am being told in other threads in these forums that if are not of the right denomination, you are a heretic, and as lost as anyone adhering to the wrong religion, or no religion.
But what I gather from your insistence that
"Without God, there is no meaning or purpose", is that, without your God, you would be sad. Would that be accurate?
Do the molecules that bind people together care about rape or lying? Are they concerned if they form cancer cells?
Not that I am aware of. What is your point?
Without God, any attempts at morality are mere illusions you create to define your own parameters.
Or, they are a particular system of values and principles of conduct held by a society, developed from and on bevaiors that are emergent in a social species.
You live in your own matrix.
Ignoring the pejorative tone of your analogy, sure, we all live in this 'matrix', particularly in the absence of evidence for the existence of gods.
