Are you talking about logic in general in this sphere or in the past before the big bang?
No, I am talking about objective reality as independent of the mind. I believe objective reality is real, but it is unknowable, because it is independent of the mind. Here:

Naturalism's axiomatic assumptions[edit]
All scientific study inescapably builds on at least some essential assumptions that are untested by scientific processes.
[43][44] Kuhn concurs that all science is based on an approved agenda of unprovable assumptions about the character of the universe, rather than merely on empirical facts. These assumptions—a paradigm—comprise a collection of beliefs, values and techniques that are held by a given scientific community, which legitimize their systems and set the limitations to their investigation.
[45] For naturalists, nature is the only reality, the only paradigm. There is no such thing as 'supernatural'. The scientific method is to be used to investigate all reality.
[46]
Naturalism is the implicit philosophy of working scientists.
[47] The following basic assumptions are needed to justify the scientific method.
[48]
- that there is an objective reality shared by all rational observers.[48][49] "The basis for rationality is acceptance of an external objective reality."[50] "Objective reality is clearly an essential thing if we are to develop a meaningful perspective of the world. Nevertheless its very existence is assumed." "Our belief that objective reality exist is an assumption that it arises from a real world outside of ourselves. As infants we made this assumption unconsciously. People are happy to make this assumption that adds meaning to our sensations and feelings, than live with solipsism."[51] Without this assumption, there would be only the thoughts and images in our own mind (which would be the only existing mind) and there would be no need of science, or anything else."[52]

The core belief about objective reality is that it is real. The rest of the beliefs in naturalism are not necessary to live in the everyday world. Hence I believe in "
that there is an objective reality shared by all rational observers.", but I am not a believer in naturalism. E.g. for logic that is a process in humans as a mental process and say nothing about objective reality itself. Logic is in the mind.
