The problem with this is that objective reality is apparently subjective.
'Objective reality' refers to the world external to the self (hence which we know about through our senses), also called 'nature', 'reality', 'the realm of the physical sciences' ─ we could add, 'the sum of all things that exist whether I'm alive or not' and so on.
The role of science is to explore reality, identify its elements and processes, describe them and set out to explain them, in each case using scientific method, which is to say, arguing honestly and transparently from examinable evidence. It also involves maximizing objectivity by skepticism, empiricism, induction, absence of prejudice. peer review, repeatable experiment, publication of results, open debate about results, and so on, It uses the definition of 'truth' that I mentioned ─ that is, it does its best to hold 'truth' to an objective standard.
It's correct that 'truth' about objective reality involves the consensus of the best informed minds for the time being, and so may vary from time to time. For example, when the bible was written, it was true that the earth was flat, and immovably fixed at the center of creation (there being no concept of the solar system, stars, galaxies or the universe as we understand those terms). Later it was true that fire is the result of phlogiston, that light propagates in the lumeniferous ether, that the earth's crust is uniform and solid, and so on. None of those things is true any more. Nor was the statement 'the Higgs boson is real' true until 2012. In QM the Copenhagen interpretation, presently the dominant paradigm, is still debated. Truth isn't absolute, just retrospective.
So that's the frame for science. What fault do you attribute to it, and what do you want to replace it with?
So objective reality is, but man knows very little about those realities.
Perhaps, but the record is clear that science knows more about reality than any alternative system of enquiry, and certainly more than religion, which has no objective test for truth and if we take just the example of Christianity has for that reason been able to divide into many thousands of sects, including Rastafarianism, Mormonism, Moon's Unification Church and a great many large and small cults and etceteras. Not even Roman or Orthodox Christianity, despite their incompatible boasts of catholicism, let alone the myriad forms of Protestantism, can agree. Those data are even by themselves a ringing demonstration that
at very best, if there's a god, that god makes no effort to promulgate any particular message as true.
For me, the reason I believe with 99.99% certainty that I have the truth, is based on many reasons, but one is mentioned here...
1 Timothy 4:7-10, 15, 16 7 But reject irreverent false stories, like those told by old women. On the other hand, train yourself with godly devotion as your aim. 8 For physical training is beneficial for a little, but godly devotion is beneficial for all things, as it holds promise of the life now and the life that is to come. 9 That statement is trustworthy and deserves full acceptance.
Self-applause doesn't cut it eg
Everything Donald Trump says is trustworthy and deserves full acceptance.
Everything Krishnamurti says is trustworthy and deserves full acceptance.
Everything Kant says is trustworthy and deserves full acceptance.
Everything Einstein says is trustworthy and deserves full acceptance.
Everything Mary Baker Eddy says is trustworthy and deserves full acceptance.
Everything you say is trustworthy and deserves full acceptance.
Everything I say is trustworthy and deserves full acceptance.
Everything anyone says is trustworthy and deserves full acceptance.
Everything ...
That's why you need a standard of truth, a test for whether any statement is true or not, which is as objective as you can make it.
What test are you using?
