Fine tuning and intelligent design are the main key figure for the existence of God. And I see how atheists are often confused to accept this. Atheists failed to negate this and haven't provide any justification for the meaning or the cause of this universe. As to put it, Sir Roger Penrose once claim that chance is impossible to be a cause or a valid explanation.

Chance would lead to a certain absurdism. And your answer is non sequitur. Chance does not explain anything.

For instance, lightning produce electric charge or whatsoever. So if it was just created by chance, you are saying that it could have turned otherwise. If we are acting today as now by chance, then it could be otherwise. God should be the designer for the existence of this universe or otherwise our idea is that unformed objects are created by chance.
