In order:

1. The Universe does not need a cause, it is part of a process. Before this Uniiverset here was something else - we don't know what and probably never will, it's not important - and after this Universe has wound down, there will be something else again,

2. If there is a Designer, they are bloody incompetent! A little extra carbon,, and and entire global ecology flies out of whack. No failsafes, no compensators, no backups shitty design. A Designer who places the most vital organ in the most vulnerable place - an idiot. In the words of the late Meat Loaf "Life is a lemon and I want my money back!"

3. See above.

4. Actually, it does, and scientists have created organic compounds from inorganic ones several times.

5. Nothing is objectively moraly wrong or right. It is morally right for a Muslim to have four wives, beat them regularly and kill unbelievers out of hand. A Chrisitan can only morally havve one wife. A Buddhist cannot morally kill anything. Morality is relative.

6. LOL! 90%of humans don't reason. They don't have anything to reason with!. They follow their bellles and groins and obey anyone who can hit harder than they can.
