The answer is: Bible

Heb 11:3

Hebrews 11:3 presents a fascinating window into the intersection of faith and the creation narrative. The declaration that "the universe was formed at God’s command" invites us to consider not just the act of creation, but the nature of existence itself. What's particularly striking about this verse is its assertion that the things we see were made from things that were unseen, resonating deeply with contemporary ideas in science, like quantum physics, which suggest that much of the universe operates on fundamental principles that are invisible to us.

The author of Hebrews, believed to be a follower of early Christianity, draws heavily from Jewish thought, marrying ancient wisdom with newfound beliefs. This chapter is often regarded as a “Hall of Fame for Faith,” examining multiple biblical figures who acted, often without tangible proof, purely because of their convictions.

Moreover, the phrasing reminds us of the creation theme found early in Genesis, where "God said, ‘Let there be light,’” exemplifying that divine word holds creative power. Interestingly, many cultures and belief systems also present creation stories emphasizing some form of unseen force or spirit behind the world’s formation, showcasing a human fascination with life’s origins that transcends borders.

In understanding scripture as both historical document and moral guide, these verses invite a discussion on existence, faith, and the mysteries that life, including science, continues to explore. Isn’t it extraordinary how ancient wisdom and modern inquiry weave together?
