Bismillah
Thank you for your question. According to our understanding of the natural disposition of human beings, humans are intimately connected to reality as they are part of that very reality and not outside of it. So since the human is connected to God, they know Him within themselves and that is why the first step to religion is the recognition of God. The path of Islam is also sometimes described as the path of natural disposition and that is because it is a path that develops that initial flame of connection into a burning fire in the smoothest and most beautiful manner.
May you always be successful
