Science is part of the philosophy of realism, which assumes that the world outside of your mind has consistent, measurable rules that are deducible.
Assuming that you buy into realism (as you should), then life has no meaning. You are one of many humans, which are a type of mammal possessing elaborate social structures and nesting behavior, having rarely constructed nests and accessories to their nests in total vaccuum, both within elliptical and hyperbolically ejecting orbits of Earth. When you expire and cease to exist the world will continue no matter what your actions your meat undertook.
