It is not that they do not have to be, it is that they are definitely not. That is supported by scripture.
Yes, now we are getting somewhere, but the world is a bit too big and to divided to be of practical inclusion.
And that is fine as long as you can integrate that with the viewpoint of countless others that are different from yours.
Ok, list them.
So you think that people who do not believe in god(s) are irrational?
Hmmm Idk Irrational is the right word, but wrong?
1. Humans are special is the universe, we violate the laws of physics with our consciousness.... how?
Our movements/reactions are not determined by physical/real means, but are determined by non-real entities/ideas. Everything else in the universe has determinism based on their initial conditions(at least to extent quantum-wise) , I would argue humans do not...
A thought experiment- You have a coin and are walking on a road that divides into two, left and right.... You decide that you are going to flip the coin and if the coin says tails-left, heads -right... You flip it and go the direction you correlated with the coin.... Physics-wise, this is truly wonderful and unique to life, Your surroundings or even the electrical signals in your brain did not determine your path, but the fictional concept of heads and tails imprinted on the coin.... you gave the coin meaning and properties it never had before, just by thinking about it... And that is what Humans do, and where they have all the power, we give things meaning, maybe that is our very purpose in the universe? To give it meaning....
I could go on and on but essentially the conclusion is... Humans, and maybe even life in general, is special and gives things meaning...
A typical Atheist view denies this property about humans and life.
This is the foundation of my belief that the Universe is Life-centric... it would not exist if life did not exist, because then it would have no meaning. There is evidence of this in the observer principle in quantum physics... the universe could very well be a blob of variance, until live observes it. Kind of like an MMO video game where the loading screens only load when you come into the facility and before that they did not exist...
I think this gives a strong case for a creator, and I would also touch on a little of Plato and other philsophers...The one over the many argument is very convincing to me.... and tying in saint thomas Aquinas that the One is whom we call god. Idk if you are familiar.... It's quite an exhausting topic that requires a lot on my part, that's why I ask if you are familiar?
How much deeper? To where?
A theological and ethical one. There aren't many Theological/religious beliefs that suffer such consequences as abortion.... most can coexist in our society.
