The realization of nature is the sign of the creator
In fact, at first, the universe did not exist. Then the Creator spreads the earth and the sea. He raised the sky, along with the sun, moon and stars. On earth there are plants and creatures that continue to grow into billions. In the ocean are fishes. In the bowels of the earth there are animals.
So for those who want to use their minds to understand clearly, it will certainly be that something that originally did not exist, then there is, then surely someone created it.
