Science needs a metaphysical basis and certain assumptions to even get off the ground:

> That there is an objective reality shared by all rational observers; That this objective reality is governed by natural laws; That reality can be discovered by means of systematic observation and experimentation; That Nature has uniformity of laws and most if not all things in nature must have at least a natural cause; etc.

Not all worldviews hold these views / make these assumptions.

It would probably be 'too much' to think about them everyday if you're going is 'doing science', but that doesn't mean they don't exist or are not important.
