How do you know there is no other planet like Earth? Obviously you don't.
smh. We've been over this. It's in Genesis and Noah's flood. That's why there is no other planet like Earth. Our probes have found it so. Scientifically, we have the fine tuning facts to show that it does not happen. Life is rare. We can use probabilities to see if we'll find another planet like ours and chances of that are slim and none.
Such conclusions are rather premature. The scientific exploration of space is really a very young science. Radio telescopes and the Hubble are relatively new technologies within the last several decades.
Nothing about the universe shows fine tuning, unless you want to represent cometary bombardment of planets, meteor strikes (have you heard of that little dalliance on this planet that occured 65 million years age), cosmic radiation, galaxy collisions, etc., fine tuning. The fact is, space is a hostile environment to life.
The discovery of life elsewhere in our solar system or elsewhere in our galaxy would be utterly devastating to the religious articles as “creation” is uniquely an earthly event. Send a probe to Mars, scan the universe with Hubble, explore space with radio telescopes and search for life off the planet Earth. This is what science is doing. What religionists are doing to establish their suppositions... well, forgive the irony, but, god only knows.
