Measurement, is by definition. That's really what measurement is, a definition process. Where the materialists flounder is when they try to define the ocean while smack dab in the middle of it...unable to see the shore. No one has really defined the universe, given it size, mass, weight, age, etc. The leading theory is that there was a time when the universe was not in existence as we know it, but that is just a wild guess with lots of problems in the guess.
you say God cannot be known by "limited instrumentation". i ask you by what "instrumentation" do YOU measure(know) God?(assuming of course that you TOO are subject to "limited instrumentation"?)
this "instrument" of yours "abstract thinking and ontological reasoning" is unlimited therefore YOU know God? why are YOU privy to this truth(unlimited instrumentation) ?
I believe in God. I am not privy to anything. It all depends on what you seek in life. A person hears about making money as a trader. They see movies, hear stories, talk to traders. Do they know what it is to be a trader? No, but they know they want to be a trader. Do you want to know God? If the answer is no, you will not seek God. That is fine by me. No one should be forced to have personal faith in a particular direction...
