Science is a tool, but many scientists don't use it properly and cling to their beliefs on faith alone.
Religion does it on faith. Science adapts its views based on what's observed and goes out of its way to find observations that conflict with its current understanding of the world. Not the same by a long shot.
Until your theory threatens their funding, then they refuse to consider your evidence and proceed blindly in the wrong direction.
Also, as a critically thinking Christian, my beliefs are indeed based on observation and I actively seek out new experiences that frequently force me to see the world differently.
Blind faith is an error that can be made by scientists and religious people alike.
