And those people would be imbeciles. Considering that the universe is far too large for the human mind to even comprehend, it would be perfectly reasonable to assume that one tiny planet in a tiny solar system would be able to sustain life.
Sigh. It has nothing to do with one random planet being able to sustain life and everything to do with the natural order and design. You can think that this is all happenstance if you are so inclined but most of us don't believe in exponential coincidences.
Of course if you believe it was all "designed" you have to explain why your loving God would put us on a planet where earthquakes, tsunamis and countless other natural disasters kill countless scores of innocent people including women and children.
There are some things which we don't understand. Belief in God does not mean that everything gets explained to you.
And if your logic is that the universe must have been designed because it is too complex to not have been designed, then we must assume that your "designer" is even more complex. But if the universe is too complex to not have been drsigned, then by the same logic, your designer must have been designed as well. This sends you down an endless rabbit hole of stupidity.
It is quite possible that our Maker was designed. I don't wonder about such things though.
There is nothing stupid about faith nor lack of faith. However when you try to equate faith to logic, it is only you who looks foolish. Yet again.
