That's because you can't make shit up in science!
Philosophy and religion are only a human method of determining how to perceive the world and how to live in it. It is all based solely on our minds. I'm not saying they're bad, but they should not hold any place in the "truth department"
And science is not based solely on our minds? Even if the things we perceive in science actually do exist -- which itself is a very contested notion, this Kantian "thing in-itself" that exists objectively in the outside world; but even if we took that as a given for the sake of argument, is it still not true that our experience of such a thing is a result of
our interaction with it? How can you possibly argue that science is the truth and only truth unless you believe your experience of the world is objective?
You can't "make shit up" in science, but neither can you remove your subjectivities from the way you perceive your environment. There are many things that influence the way we see the world, and those things are inherent within us; they make a part of who we are. Unless you can remove yourself from your place in the world, you cannot possibly be objective -- and not only is that impossible, but not even desirable.
Science is a human, historical method that developed during the Enlightenment.
