A quick "bump" on this question as I think it's relevant:
Evolution attempts to understand ONE-TIME events in the distant past which have NEVER been observed......
Yahweh's creation of the world....would that not also count as "ONE-TIME events in the distant past which have NEVER been observed" and should therefore be subject to the same scrutiny and caveats that you would apply to evolution and dating of the Earth?
1) Accurate eyewitness accounts.......
Okay - I'm intrigued. Looking at my Bible, I see that the Earth (with division of land and water, and addition of plants and animals), and the sun and moon.....were all created BEFORE any human being was created. Even assuming Genesis 1 is accurate, can you explain where the "eyewitness accounts" of the creation of the world come from?
2) Supernovas – According to astronomical observations, a supernova occurs, on average, every 25 years in our galaxy.
As AoB said....50 years
1 - but please cite your source for this figure.
A Supernova first explodes (stage 1), then expands rapidly for about 120,000 years (stage 2) ....
Okay, just going to stop you there, just to check some assumptions.
First off, the Speed of Light. When we look at the night sky, we don't see the stars as they are now - we see them as they were in the past. At best, around 3 or 4 years ago, but potentially hundreds of thousands of years ago. I'm presuming that you are happy that the speed of light in vacuum is a constant, and that it has not altered dramatically over the last few thousand years?
In fact, we observe only 200 such supernova remnants,
I'm presuming also that you are assuming that every quarter of every part of the sky has been completely and throughly examined and catalogued? And that you agree that the apparatus used to locate and classify supernovae has been at the same high level of accuracy throughout the time it took to catalogue the entire sky? In other words, that the entire sky has been scanned with equipment capable of detecting remnants that are hundreds of thousands of light-years away?
If the galaxy is 6-7000 years old, then we should observe about 268 remnants.....
Indeed. One of the remnants we observe is SN 1987A, measured at approximately 168,000 light-years distance
2. (Again, happy to see your source) But....if everything was created just 7,000 years ago, how could that possibly be? (c.f. my earlier point regarding the speed of light). How do you account for the fact that one of the remnants used to support your 7,000 year old universe is far too old to have ever existed?
3Final question: is the rate of formation of supernavae constant, and did they start to form "right at the beginning" (so that the first supernova happen during Year One? Or does the rate of formation vary with the age of the star and its magnitude, so that none could begin to form until a certain point in their lifecycle had been reached? If every star has the same lifecycle, should not every star have gone nova at exactly the same day, given they were all
created on the same day?
1 http://www.esa.int/SPECIALS/Integral/SEMACK0VRHE_0.html2 http://heritage.stsci.edu/1999/04/fast_facts.html3 It is, of course, entirely possible that the age of the earth, and the age of the universe, are two entirely different things, which would allow for stars to be created thousands or millions of years before the earth was, to give them "time" to reach supernova status. But....that would contradict the literal 7-day telling in Genesis, of course. No problem with that in and of itself....but, of course, if those literal seven days were NOT literally seven days, then the 7,000 year calculation taken from the creation of Adam therefore will relate ONLY to the time man has spent on the Earth. Once you have discarded the literal 7 days of creation, you can no longer say that Adam to now being 7,000 years still means that Adam to now plus one "Biblical creation week" is still just a hair over 7,000 years.
A big problem, I think, if you want to simultaneously assert "eyewitnesses of creation" (see top though) AND a constant speed of light. But maybe you don't?
