Although I share your point of view w.r.t. scientific thinking and I don't disagree on objective reality (personally), this question can still be answered in a different way and may lead to the conclusion that objective reality is a construct that gets created by perceiving.

Subjective idealism states that there don't has to be objective reality to get truth values from it. Trying to understand this from a materialistic point of view is not easy because those philosophies are basically in contradiction to each other.

It's just important to realize that the belief that objective reality exists is one of many points of view.

How is "100% secure" defined in this context if you can't prove it?

In a sufficient complex logical system Gödel's incompleteness theorems are turning relevant. It might not be possible to prove some aspects of it if the system is logically consistent. This may also apply if you model reality in a logically consistent way. Logics has its limits.

Although I agree with you, I think it's important to realize that our positions are and can't exceed to be beliefs or even strong beliefs called facts.
