Its probably extremely low. But even if it’s one in a trillion. It will happen if there are enough iterations of events.
Even in lotteries of 1 in 100 million chance in winning. If you have 500 million people purchasing tickets then the likelihood of a winner is very high even though the probability of a single ticket on its own is low.
From what we understand about the universe so far it’s not possible for the universe to come from an intelligent creator/god. That’s why scientists do not take it into considerations when answering questions about the origin of the universe.
According to Drakes Equation >
Only one in a million million has the right combination of chemicals, temperature, water, days and nights to support planetary life as we know it. This calculation arrives at the estimated figure of 100 million worlds where life has been forged by evolution.
If you want to call it a coincident I really don't have much of an argument to make since this possibility is much less than your mind or senses making a mistake.
As I mentioned earlier Science and Religion have two different realm and scope. So scientists don’t need to take God into consideration for the origin of universe. However you said that
“what we understand about the universe so far it’s not possible for the universe to come from an intelligent creator/god”
I am afraid its your claim & may be of some other scientists too but certainly not all of them.
By the way since you are making this claim can I ask you for the proof??
As you can see, most of the famous physicists and scientists had different opinion than yours. They were NOT atheist.
Examples are Newton, Leibniz, Addison, Einstein.
Can you please tell me if they were wrong in their judgements? If yes. How & why?
