This idea that looks at all of the seemingly "perfect" conditions here on earth for life as we define it to survive and thrive, such as temperature, distance from the sun, proportion of matter, existence of and abundance of liquid water, the amount and capabilities of our atmosphere, etc, etc
Many creationists cite those, and many other seemingly perfect conditions as PROOF that we were created, and the earth created for us. Yes, life on earth is a delicate balance. We would die off if any of those conditions were slightly different. It seems to be a compelling argument...
BUT science and evolution say that we evolve to fit our surroundings. Those less optimized for their surroundings die, leaving those more adapted, more successful to be the sole reproducers, and only the survivors pass on genetic material. In this way, life is sculpted to fit surroundings perfectly, until we look at it, and think the surroundings were sculpted to fit us.
With changes in the conditions, so does the life that can be supported in those conditions. It won't be like us, but it will be life, just different. Just like this bacteria that has survived without phosphorus and instead substituted arsenic in its' DNA is
at least evidence that such life can exist and survive in what we would call "harsh" conditions on other planets.
At most this bacteria might be found to be proof of two separate instances of life evolving, and that we share no common ancestor with this bacteria and that it indeed evolved separately from us.
Boom!
