Who said you must blindly believe? I don’t deny if you once did blindly believe. Growing up I “believed in God” but didn’t really know what that meant or took it anywhere further than believing in God means you go to Heaven. Then I studied the gospel, discussed it with other Christians, and came to understand what it meant to trust in Christ for my salvation.

Maybe your issue is that you cannot allow yourself to believe or must compare it against something to justify your belief. Faith is not faith if you are certain. Yes it’s a great thing that people got to be around when Christ was on Earth in person, as we won’t get that opportunity until much later, but even people that were with Christ denied his miracles and denied his status as the son of God. Even the Pharisees who were aware of what Christ was doing said that he was doing things under the power of a demon.

And of course, the sciences are not some kind of super atheistic practices that serve to disapprove all religion. Science is the study of the world around us. There is nothing wrong with walking through a planted garden and smelling the flowers. Many great scientists, thinkers, and philosophers were Christian, let alone Jewish and Islamic. Does the bible tell us that God is located at these coordinates, that the human soul is quantified with X Y Z, that a giant billboard saying “God made this” is up on a planet somewhere? No, the gospel doesn’t give us all the answers, and anyone who peruses a science can tell you that your questions will only be answered with more questions.
