Science at its best is an open-minded method of inquiry, not a belief system.
The assumption that the laws of nature are eternal is a vestige of the Christian belief system that informed the early postulates of modern science in the seventeenth century. Perhaps the laws of nature have actually evolved along with nature itself, and perhaps they are still evolving. Or perhaps they are not laws at all, but more like habits.
For more than 200 years, materialists have promised that science will eventually explain everything in terms of physics and chemistry. Believers are sustained by the faith that scientific discoveries will justify their beliefs.
There's a certain kind of scepticism that can't bear uncertainty.
