The secular definition of “believe” is to accept something as true. Whereas the Christian definition can be found in Hebrews 11:1 – “Now faith is the assurance of things hoped for, the conviction of things not seen.”
Science was never meant to take on religious tones. We all believe in something, and we all wrestle with unknowns, meaning, and purpose. The truth is important. Science, over the course of history, has often gotten things wrong. Human reason (aka science) is fallible because people are fundamentally fallible.
It is in our DNA to make things better, but the pursuit of science or technological advances can give one a false sense of control. There’s also a drive within scientific pursuits to make a name for yourself. To have a theory or principle named after you is a way of leaving a legacy behind after you are gone. It is an attractive sense of immortality.
The problem lies with that there is never enough – never being satisfied. There’s no contentment or peace. There’s always the pursuit of more, better, higher.
God knew this was not the best way for us humans, just look at the story of the Tower of Babel:
Now the whole earth had one language and the same words. And as people migrated from the east, they found a plain in the land of Shinar and settled there. And they said to one another, “Come, let us make bricks, and burn them thoroughly.” And they had brick for stone, and bitumen for mortar. Then they said, “Come, let us build ourselves a city and a tower with its top in the heavens, and let us make a name for ourselves, lest we be dispersed over the face of the whole earth.” And the Lord came down to see the city and the tower, which the children of man had built. And the Lord said, “Behold, they are one people, and they have all one language, and this is only the beginning of what they will do. And nothing that they propose to do will now be impossible for them. Come, let us go down and there confuse their language, so that they may not understand one another’s speech.” So the Lord dispersed them from there over the face of all the earth, and they left off building the city. Therefore its name was called Babel, because there the Lord confused the language of all the earth. And from there the Lord dispersed them over the face of all the earth.GEnsis 11:1-9
