“The heavens belong to the Lord, but he has given the earth to all humanity” (Psalm 115:16, NLT).
In the Star Trek world, Class M planets can support carbon based life. Their atmospheres are composed of nitrogen and oxygen and they have an abundant supply of water. We don’t have warp drive technology and can’t travel the universe, so as far as we know, earth is the only Class M planet, at least in our galaxy. There is evidence of water on Mars, but it’s a small amount and it’s frozen, not enough to support life.
Even the Star Trek writers knew not to over do it by making all the planets they discovered M Class. In that fiction, most were uninhabitable and even hostile. Our earth is just the right distance from the sun, has just the right tilt and the exact components necessary for life. It’s a rare jewel in the cosmos and an amazing gift from God. We too often take it for granted, but the space travelers never did. They seemed to always breathe a sigh of relief as a life-welcoming and supporting planet came into view. May we be thankful every day for God’s wonderful gift of our delightful home.
