Obviously, a Supreme Being or Divine Group of Them intelligently designed everything intelligently designed around us, which obviously-existing natural phenomena we obviously were born into and obviously did not create ourselves.
As to the Identity of that Who or What created it all back in "the beginning" (whenever THAT was) is not readily obvious by observing natural phenomena, being that nothing natural and non-manmade is stamped with an inception date.
Obviously, certain characteristics of that Who or What Creator are obviously perceivable by the created phenomena He, She, or It has intelligently designed. For instance: the awesome power, creativity, complexity, repairability, consistency, durability, extensiveness, beauty, reliability, precision, impeccable order, and trustworthiness of natural phenomena!
Enter the 66-book "Holy Bible" - a rather lengthy and complex assemblage of human-authored plain common sense, historical records, and bizarre assortment of Ripley's Believe It or Not claimed "signs" and "miracles."
It has been said by some humans that the Being is designated male in gender, with "God," "the Lord," "the LORD," "Christ," and "Jesus" as [His] name. Associated with them are "the Holy Spirit" ["Who" - not What] convinces believers who have "faith" of the previously-stated declarations and the contents of "The Bible" elaborating on the alleged actions and specific doctrines relating to such named entities.

(Both Lazarus and Jesus were not dead, according to "the Bible," for more than five days). I never saw the Red Sea opened up by a strong wind, never seen Joshua's purported "long day" nor the sundial shadow of Ahaz abnormally going the opposite direction. Medical science has made great strides in enabling the disabled and handicapped lame to walk, the blind to see, and deaf to hear. But I have never seen anyone walk on water, except ski behind a powerboat either barefooted or with a pair of water skis. Making enough food to feed 5000 humans with a few slices of bread and a couple fishburger patties sounds like a neat trick, to be sure.
Then there is what Saint Paul might have called "the foolishness" of some "scriptural" premises, such as:
