The Earth
One famous interaction about the earth and space (that is accredited to different sources) goes something like the following,
A well known scientist once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun, in turn, orbits around the centre of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: "What you have told us is rubbish. The world is really a flat plate supported on the back of a giant turtle." The scientist gave a superior smile before replying, "Ah, but what is the turtle standing on?" "You're very clever, young man, very clever", said the old lady. "But it's no good, it's turtles all the way down!"
Rather than turtles, it's gravity that holds the Earth in a fine balance. The Bible says that "He spreads out the northern skies over empty space; he suspends the earth over nothing." Job 26:7
We live on an amazing planet.
If the Earth was 5% closer to the Sun, all the water would boil away.
If the Earth was 1% further away, all the water would freeze.
The rotation, gravity and speed of the Earth is necessary to maintain the atmosphere, without this life couldn't exist.
The Earth's Magnetosphere (the magnetic field caused by the rotation of the iron core, illustrated below right) protects the Earth by deflecting most of the Sun's Solar Winds, without this Earth's atmosphere would be swept away.
Is the Earth in a fine balance pure chance, or is there a Creator?
Isaac Newton wrote of theology and science. In his work titled, "Principia" he said that,
"This most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being. Atheism is so senseless. When I look at the solar system, I see the earth at the right distance from the sun to receive the proper amounts of heat and light. This did not happen by chance."
The Bible says in Isaiah 45:18 "For this is what the LORD says - he who created the heavens, he is God; he who fashioned and made the earth, he founded it; he did not create it to be empty, but formed it to be inhabited - he says: "I am the LORD, and there is no other.""
And in Psalm 19:1-3 "The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they display knowledge. There is no speech or language where their voice is not heard."
