A lack of evidence that God exists, is not evidence that the opposite is true. A person saying they are an atheist due to a lack of evidence, is being illogical and irrational, because they should be undecided. But an atheist has decided there is no God, when there is no evidence for that belief. This supports the position that a lack of evidence has nothing to do with atheism. Atheism is an emotional decision that a person makes and uses their intellect to try to support and defend it. If it were rational, they would be agnostics, not atheists. This explains why so many atheists don't recognize, near death experiences, and born again experiences of people seeing God, as evidence. Atheists don't see the Bible as evidence, medical miracles as evidence, reports of religious visions, or prophetic dreams, as evidence. They have already made up their minds there is no God, for emotional reasons, and their rationale that there is no evidence, stands, no matter what evidence is presented. All the evidence does not count, for some reason or another.
Anything with a beginning has a cause, and the universe has a beginning. This has been shown by astrophysics, therefore, the existence of a Big Bang is evidence that there is a God, because there had to be something to cause the Big Bang to occur. God does not have a beginning because he is an eternal being that exists outside of time and space. In the first moments of the Big Bang, energy, space, time, and matter came into existence. God, on the other hand, is an eternal being, and the creator of time, space, matter, and energy. God does not, and cannot, have a creator, because God is "before" time itself. Since God created time, there cannot be anything "before" God.
The order, complexity and stability of the universe infers a grand design. If every house has a builder, certainly something as complex and ordered as the physical universe has a builder. The order, stability, and complexity of the universe is evidence of an intelligent design, and therefore, God.
Life cannot come from non-living matter. The existence of life necessitates an eternal living God to create life, so is evidence that God exists. Amino acids don't just fall together to form complex chains and proteins. Proteins don't just fall together with fatty acids to form cell walls. Life is far too complex to happen by itself. It would be like saying falling paint over a billion years could result in the Mona Lisa. Art necessitates an artist, and the universe and life, necessitate God.
Too many weird things happen for there not to be a God. Not just documented miracles, but bizarre coincidences that should never happen. This is evidence for a purpose behind seemingly random events. God is the origin of the design and purpose of human life in the universe. The apparent intelligent design of the universe is evidence that God exists. There appears to be intrinsic meaning and purpose in life. That life has meaning and purpose is evidence of God.
Concepts come from our experiences. Human beings should not have the concept of a perfect, pure, eternal, omnipotent being, yet over 85% of the human race does. Since everything we know and conceive is derived from our experience, the existence of the God concept is evidence that some such being actually exists. This is not just idealization, conceiving of the greatest of all, or a combination of existing forms. God is outside the box, in the sense of not just the oldest or the first, but eternal, outside the time space continuum, perfect and pure. Either God exists or the question would be absurd. The question of God is not absurd, therefore God exists.
The fact that the vast majority of human beings believe they can communicate with such a being and that being can communicate with them, is evidence that something exists. Billions of people, the vast majority of the human race, the most intelligent species on the planet, testify to having a direct, supernatural, experience, in one form or another, with the divine. This eye-witness testimony is evidence that such a being exists.
The only thing left to speculate on is which version or concept of God is the correct one. Since God is beyond the physical universe, it stands to reason that none of the human versions are 100% accurate. So this leaves us only to wonder which religion is the closest to the truth.
