The heavens declare the glory of God; and the firmament sheweth his handywork. Day unto day uttereth speech, and night unto night sheweth knowledge. Psalms 19:1-2 KJV
Simple observation or detailed study of the creation demands of one to recognize that a Creator exists. Just seeing a watch or an automobile should cause a person to realize that there must be a maker.
Someone had the idea, the vision, and began to materialize the product.
Our verse today states that man is without excuse when he rejects the notion of the Creator of all things in that the mere existence of such intricate and diverse design shows the existence of the Designer.
The Bible tells us what the heavens declare.
Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear. Hebrews 11:3 KJV
In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made. John 1:1-3 KJV
