That's not a far stretch from something theists of various flavors like to argue, about how the fine tuning of the universe also implies intelligent design. You can just as easily invoke something like the anthropic principle, we find the universe is the way it is because if it wasn't, we wouldn't be around to think about it.
<A lot of words>
I really am not sure what you are taking issue with in my post. I'm pointing out that FET doesn't imply intelligent design much more so than RET, as both schools of thought have very fine tuned mechanics that make life as we know it possible.
Conditions for life only appear fine-tuned because we evolved to settle the niche provided to us by our environmental conditions. I don't think Flat Earth holds up to the Anthropic Principle let alone any real observational or investigative evidence. There was life on Earth before there was any Oxygen in the atmosphere. Humanity is just another species of animal that evolved to occupy an environmental niche. Any notion that humanity is special or different or ascended in any way is just ignorant, it's nothing more than anthro-ego.
The thought that our whole world is just a speck of dust trailing a speck of light in a galaxy that is just another speck of light in a vaster web of entwined galaxies, might be depressing. When you understand the scale of the universe you realize how little you matter, how little everything and everyone matters.
For the God-fearing types, it should inspire terror. It would mean God is much, much, much mightier than He is presented in the Bible. It means the effort He invested into the creation and curation of this world, is no different than the effort He invested into the creation and curation of a Trillion other worlds. All with intelligent life and all those without, all part of Gods plan, Quintillions of lives shaped into being by His hand. I can see how this is a hard pill for religious believers to swallow, the God of the Bible is an insignificant powerless speck compared to the true scale of the Universe.
But when nothing matters, you know what that really implies? It doesn't mean that you should kill yourself and get this pointless existence over with. It means that there is no scale of greater or lesser meaning. When nothing matters, all things matter the same. A baby's first words, a black hole consuming a passing star, having lunch with your colleagues, the political affairs of a galactic empire, the breeze through a wheat field, a dog making friends with a kitten, the extinction of all living things - they all matter the same. And I think that is a beautiful way to approach life, and is far from the oppressive nihilism people seem to think plagues atheism.
