The question should be instead do we have evidence denying God's existence?

Think about your phone, watch, jacket, or even a simple bottle of water. Did you believe that all these things came into existence out of nowhere or as a result of some random events? Have we ever seen something which came from absolutely nothing?

So what about other things we see that are far more complicated such as small atoms, humans, animals, and all these complicated creatures living around? 

The more science evolves the more it reveals about the complexity of the human being; here is a National Geographic video about that:

Humans are only a tiny part of a magnificent system, where millions of other species with different designs and complexity, all living in harmony and equilibrium. However, humans are blessed with superior intelligence which grants them the ability to consider the complexity of this whole creation and its purpose.

Looking at the bigger picture, the earth itself is a very tiny part of the universe.... Here is a short video of how the Earth is compared to the rest of the universe

These facts should definitely make us curious about who created all of these and what was the intention behind these creations? We cannot afford to ignore such questions.

"Indeed, in the creation of the heavens and earth, and the alternation of the night and the day, and the [great] ships which sail through the sea with that which benefits people, and what Allah has sent down from the heavens of rain, giving life thereby to the earth after its lifelessness and dispersing therein every [kind of] moving creature, and [His] directing of the winds and the clouds controlled between the heaven and the earth are signs for a people who use reason" 

Quran: Chapter 2:Verse 164

Religion was communicated by Allah to humanity through his prophets ADAM ABRAHAM, ISSAC, JACOB, MOSES, JESUS...and last of all MUHAMMAD peace be upon them all. Those were the best people who lived on earth; they are our role models and were sent to guide us. They were all preaching the same message and that is:

THERE IS ONLY ONE GOD AND HE ALONE IS WORTH OF WORSHIP.

Say, ˹O believers,˺ “We believe in Allah and what has been revealed to us; and what was revealed to Abraham, Ishmael, Isaac, Jacob, and his descendants; and what was given to Moses, Jesus, and other prophets from their Lord. We make no distinction between any of them. And to Allah we all submit." 

Quran: Chapter 2:Verse 136
