There is Naturalism, "the idea or belief that only laws of nature (physical law) (as opposed to supernatural or spiritual) and forces operate in the world; the idea or belief that nothing exists beyond the natural world", though only you can say if it is entirely your viewpoint.

Is talk of irreligion allowed? Because Naturalism is considered an irreligion, with subtypes of its own, including Metaphysical, Humanistic, and Methodological.

I think Secular Humanism (also an irreligion) might be a good fit for you though; it embraces Naturalism and posits that each person must examine for themselves their relationship with ideology, instead of accepting any of it point blank:

The philosophy or life stance of secular humanism (alternatively known by some adherents as Humanism, specifically with a capital H to distinguish it from other forms of humanism) embraces human reason, ethics, and philosophical naturalism while specifically rejecting religious dogma, supernaturalism, pseudoscience, or superstition as the basis of morality and decision making.

It posits that human beings are capable of being ethical and moral without religion or a god. It does not, however, assume that humans are either inherently evil or innately good, nor does it present humans as being superior to nature. Rather, the humanist life stance emphasizes the unique responsibility facing humanity and the ethical consequences of human decisions. Fundamental to the concept of secular humanism is the strongly held viewpoint that ideology—be it religious or political—must be thoroughly examined by each individual and not simply accepted or rejected on faith. Along with this, an essential part of secular humanism is a continually adapting search for truth, primarily through science and philosophy. Many Humanists derive their moral codes from a philosophy of utilitarianism, ethical naturalism, or evolutionary ethics, and some, such as Sam Harris, advocate a science of morality.

Still, in the end these are all just labels, although you may find one that fits you. Good luck!
