HOW and WHY is earth so perfect? Biologically and cosmologically...Is it God?

OMG yes! And Ebola is yet another wonderful example. So beautiful! And look at how it turns an innocent childs intestines into soup within a matter of hours! OMG the beauty! And everyone is so attractive! We could all be movie stars! And the Flu virus is wonderful too. Gotta catch 'em all! And oh how beautiful cyanide is! Glorious!

So yeah. Nothing is as perfect as they'd have you believe. Nothing is fine-tuned perfectly. There's actually a great margin of error that could've occurred that wouldn't've really changed much of anything. And your assumption that this planet is the only planet that supports life in the entire universe is false and borne of ignorance.

Yes, this is the work of God. I've many times come across scientists saying the universe does appear fine-tuned, and that's why many of them believe there must be many universes and we just happen to live in the right one. But the Bible tells us in Romans 1 that God has made it perfectly clear in nature that He exists.

And here's another interesting coincidence for you, if you haven't heard of it, that I've seen creationists point out. We only have the eclipses we do because the sun and moon appear to be about the same size:

"The Sun's distance from Earth is about 400 times the Moon's distance, and the Sun's diameter is about 400 times the Moon's diameter. Because these ratios are approximately the same, the Sun and the Moon as seen from Earth appear to be approximately the same size: about 0.5 degree of arc in angular measure.[6]"

Perfect???? Are you stoned????

Look, most of that is really easy to shoot down. Earth gets further from the Sun every year. It's not a perfect distance. It's days are getting longer because the Moon is moving away scrubbing off some of that energy. So it's not spinning at any perfect set amount. It rains on Venus, so that's not unique.

We fit here because we evolved here. We'd have died and something that did fit would be here if we didn't fit.

Fill a shot glass with water.

Was the shot glass made to hold that particular ounce of water? Or did the water simply confirm to the shape into which it was poured?

The apparent "fine-tuning" of the universe is the same. We are as we are and the universe...and Earth...had to be the way they are to give rise to what we are. If other conditions were present, we might be very different.

The earth is far from perfect, biologically or cosmologically. The only people who think it's perfect are those who get all their science information from creationist sources. Those who have studied science in more detail, especially at the college level and above, know just how far from perfect the earth is.

That, incidentally, is why it's so hard to believe that you're agnostic. You're spouting all the usual creationist propaganda.

It is suited to the kind of life we see on Earth. Different laws wouldn't necessarily prevent life, but it would be different life. The life we see fits Earth because it evolved in terms of Earth's laws, not because the laws were not created for the sake of life.

And nothing about it is "perfect."

Your final sentence is either a truism or simply false. it is a truism if you want the exact history of Earth repeated. It is simply false if you're saying nothing like Earth could exist anywhere else.

Earth is not perfect. In 5 billion years, the Sun's radius will extend to Mars because of the hydrogen's conversion to helium in the core. Earth will be a goner

Obviously it must be the work of the Abrahamic God, and no one else.
