The Ship is sinking!

Picture your self on a cruise at sea. It's a beautiful sunny afternoon as you stand on the deck of a gigantic cruise ship in the middle of the ocean. You gaze deep into the distance and see absolutely no land in sight. You glance down at the side of the ship and to your shock and horror you see a massive hole on the port side of the cruise liner. You quickly alarm everyone with a loud frantic voice" We're sinking! THE SHIP IS SINKING!" You even tell every crew member you can find. You tell the captain about the massive hole but the captian says "sorry there can't be a massive hole otherwise we're all gonna die!" and then goes on about his business as though you had never said a word.
This short story is in some ways analogious to many theistic arguments.
Example 1 (Blah) must exist or there is no objective morality.(Whatever that is)
Example 2 (Blah) must exist or there can be no objective meaning,purpose.(Again whatever they mean by objective)
Example 3 (Blah) Must exist or there is no freewill(and yet again whatever they mean by that!)
Example 4 if (Blah) doesn't exist then life is futile because in 4 billion years the sun is going to destroy every living thing on this planet ,therefore Blah(god) exists.
I hope you can see the fallaciousness of such arguments! For example even if without BlahWeh(God) there was no objective morality or universal ought doesn't mean either of them exist!
Reality/truth/existence is indifferent to what you want to be the case. It is what it is regardless of your desires and feelings.
Instead of wishing on a star or some sky dady ,I think it better to embrace existence for all of its ugliness and beauty! And to be humbled by our true place in the universe instead of living in a dream land. Perhaps if the Captain had been honest with himself about his plight ,he could have done something about it.
