Why Fight the Young Earth?

Question from Jerry:
I very often hear about if the Earth is ~6000 – ~10.000 years old or if it is billions years old.

But I don’t understand how this is an argument, just because in the Bible it says God created the heavens and the earth and all live on the Earth in 6 days.
So.. if Adam would do scientific research on the universe and the planet, would the planet look like its only a couple of days old?
I can’t imagine how that would look like, because scientifically, a 6 day year old planet would look nothing like a planet, more a ball of lava.

So If God created the Earth to be habitable, it would HAVE to be a billion year old planet, there is no other choice. So of course the planet looks old, even if it’s created just a second ago.

So many atheists use the evidence for an old Earth as an argument against Creation. I don’t see how it has any argumentative value though.
I’m wondering what an atheist’s response to this is.

Thank you ever so much 🙂

Answer by SmartLX:
Young Earth creationists (YECs) do say that God created the Earth more or less the way it is, without working through the lava-world phase over millions of years. As you say, there’s strong evidence for an old Earth (geological, astronomical, radiometric, etc.), so a young Earth would have been created with all that evidence essentially falsified. This is the problem though, because why would God go to so much trouble to deceive us into thinking it was so old? Especially if we’re supposed to take the roughly six thousand year history of the world in the Bible seriously?

Of course the problem with any anti-religious argument that goes, “Why/how would God do this?” is that it’s possible to assert as gospel (sometimes literally) any answer which explains it away. The Earth looks old because God’s testing our faith, for example. Thus faith is insulated from any attempts to make their beliefs sound silly, and plot holes in scripture can be ironed out.

The main point of this particular battleground is that young Earth creationism follows on from Biblical literalism. The Bible says the world was created in six days, and that there have only been a small number of generations of humans since then, so that’s the way it was. There’s no good reason to believe it except if you want or need the Book of Genesis to be literal. Outspoken YECs try to convince nonbelievers that the world is young so that they will accept that God created it, because supposedly nothing else could explain a young Earth. Even if they fail, they often succeed in reassuring other Biblical literalists.

To give their position a respectable veneer, in order to appeal to nonbelievers and impress believers, YECs need to make it look like it has secular scientific support, which means presenting scientific arguments that the Earth is young. The proper use of the real evidence that the Earth is old, rather than to jump straight to advocating atheism, is to simply counter these arguments by YECs, and the evidence does so very easily. Thus there is no intact evidence for a young Earth, YECs are reduced to claiming God made the world look old, the young Earth becomes a mere assertion and it cannot serve as a solid premise for arguments for the existence of the God of Abraham. Thus you can believe in a young Earth if you want but it won’t get you anywhere with those who don’t already agree with you.
