I suppose I am an agnostic. I believe that religion has clearly been invented by humanity becuase of our fear of the unknown. meaning what happens when we die. Probably nothing. We cease to be. If that is the case, how can you fear nothing? There is even now, rational and plausible theories by esteemed scholars that suggests, christainity was instigated by the Romans themselves. Easier to control an Empire if everybody adheres to the same doctrine. Anyway as I say I am an agnostic, because in light of all I say above, I and nobody else actually knows what happens to our conscious when we die. Do we have a soul? Does such a concept exist? Who knows. What I do know, is it is complete mumbo-jumbo to believe in an all - knowing intervening deity that made this. This! A world of injustice, cruelty, suffering. poverty and inequality. Where the rich are rewarded, we have wars, hunger and little children suffer. A good deity done that? Please! It is complete nonsense. No. Religion is nonsense. But when we die who knows. maybe we are part of nature. We are electrical singles and carbon. maybe we just connect again through nature with other living things. who knows. Anyway that is some opening thoughts.
Sounds like you are atheist, not agnostic. Not knowing what happens after death is one, but not all, the claims of theism. For example, it may be that gods exist and when you die you are deemed "unworthy" and cease to be while other "worthies" go on believing.
If you were agnostic, on the other hand, you wouldn't believe or disbelieve that religion was invented by humans: you would be "on the fence" as it were until such time it can be proved either way.
