Hello maybe because of two reasons, when we look at the universe we cannot understand or explain how these things came to be, Psalms 8:4. Our quest for knowing the things of God can really be questionable. If you can see things that are beyond our comprehension sometimes it is just easier to let it be, Romans 11:33-36. But when we realize that we are not perfect it would be a good idea to understand how a sinner would behave.
Another point would be that we do not know what to acknowledge when it comes to God, is it physical or is it spiritual? How should we look at things, what should we look for? When we look over the life of Jesus Christ what was he really telling us about God’s power or if he said nothing? These things are important since they help us understand God, Exodus 33:17-20.
God is seen from a human standpoint from the life that was created, and the power given to humans to reproduce, Romans 1:18-23. This is of course not our own works but the works of God, Psalms 100:3. Because we can acknowledge living things around us, we can see God's intelligence, wisdom, design, forethought, etc.... That life was created and thrives every day is a view of God' awesome power, Revelation 4:11.
