The disparate techniques were bridged and calibrated by cepheid variable stars. A number of other techniques have since been developed to measure astronomical distance. This site mentions water masers and analysis of star clusters. The more measures we have giving agreeable answers, the more confidence we have.
You keep your understanding too simple so that what you understand can stay wrong. In short, wilfull ignorance.
Willful. Must ewes spell checker!
"Exorcize your Morton's Demon!"
My understanding may be simple in some cases. It's been over 20 years since I had college astronomy, and I only had the one course in that field. I don't remember Cepheid stars being discussed. But I will admit it sounds logical. It's still based on assumptions that we know how light acts over long distances and thus difference in magnitude is an adequate surogate for distance.
The problem here is not the long distances. It's the assumption that long distances prove that God didn't make the heavens and the earth, in a 7 day period like He claimed.
The very first lesson on deception in scripture was that of Eve in the Garden. Satan flat out contradicted God and told her that she wouldn't die, followed by a lot of things that were true. Instead of focusing on the contradiction, Eve focused on the things that Satan had told her that were true and it made the lie palatable.
The long distances evolutionists point out are probably reasonably accurate, the constancy of the speed of light may be true too. However, they do not negate what God said about His making the universe when He said He did. There is an explanation for why things appear as they do. I'll look for the flaws in your observations and logic where I can find them. But at the end of the day, I'm going to believe God.
That's different than Morton's demon. I don't filter the evidence. But the evidence and man's understanding of what he sees is not strong enough to negate what God said.
Morton's problem wasn't the filter. It was that he had no absolute truth to measure by. Thus when Morton finally bypassed the filter and saw observations that at first glance contradicted his world view, he changed his world view. Convenient, yes, but he has no firm foundation. He'll be blown about by every change in the wind. He doesn't know who he is or where he came from. Is he Neanderthal's child?, or Cro Magmon's? or Lucy's? or trunkmoney's? He's got no clue. He's counted his Creator a liar based on things he doesn't fully understand.
I, on the otherhand, know the Creator of the Universe. If He says His written word is true, and His written word appears to say the earth is young, then my money is on a young earth. There's always the possibility I misunderstood something. But just because light as we understand it would take millions of years to get from where we understand the stars to be, using the physical laws as we understand them, does not in any way convince me that we fully understand the how and why and timing of God's creation.
