Welcome. It is good that you are looking for answers, because as you have found out many are more interested in justifying their biases.
It is my understanding that there are three basic disciplines required to understand Reality or Life, they are Philosophy, Theology, and Science, not necessarily in that order. Science deals with facts and nature, Philosophy about the mind and how we know, and Theology about purpose and meaning.
Most atheists believe that nature is purely physical, when it is obvious that nature is also rational. As Einstein said, "The most incomprehensible thing about the universe is that it is comprehensible." Matter/energy cannot think.
God is not a failed hypothesis, but God is not a supernatural answer Person. God is the Source of all that is. God is the Source of the Big Bang. God created the universe, matter/energy, time and space, purpose and meaning where and when there was nothing, ex nihilo.
While this cannot be proven beyond a shadow of a doubt for the professional doubters, the Big Bang is the smoking gun and God does indeed exist, because God and God alone could have created the universe out of nothing. What this means is not that we are right, but we are all in this together and we need to work together lest the universe collapse under the weight of our arrogance and indifference to the needs of others.
