How do you know God doesn't care? You are tackling the most unexplainable and deep mysteries with far too much conviction and certainty. Though I applaud you for your opinion, it's a bit unscientific, no? lol. It's why it's called "Faith". Yes, difficult to prove but equally difficult to disprove.
The concept of God, the all knowing, the majestic existence and capabilities of God are well beyond Mans grasp. Consider how much we can't explain right in front of our own eyes, and then consider the abstract, unknown of God. It's far too difficult.
Scientists have stuided the Synchronous fireflies for decades, they still cannot understand how they coordinate. There are singing whales, scientists scratch their heads. There are simple plants which humans don't fully understand, don't even get me started on the human body and in particular the human mind. All at our disposal, with science methods, some dedicating their lives to understanding various concepts and realities in our world, and no answer.
All of these entities are right in front of us. We have no shortage of exposure to them, and there are hundreds of thousands more one could list, yet, we don't understand them. Sometimes our understanding is so limited it is embarrassing considering how much effort we have espoused.
To me, many of these mysteries are so complex that they had to have come from a Creator. Nature alone is baffling and absolutely astonishing, the unexplained in nature takes it to another level. God is the greatest unknown and unexplained. Certainly whether he cares or not well beyond our grasp.
