Because you really haven't answered the questions or supported any of your positions. It's a key point in the thread and the topic.
I believe that you believe you have supported an assertion, but so far you have introduced no evidence or even logic to back that up. If you want to just say that you don't believe evolution as a matter of faith, then that's fine. It's a matter of faith and so no one expects you to support it.
But when you say the brain is too complex, you've moved into an area of judgement, testing, standards. Then it is valid to ask you to support your opinion.
Some things you need to address would be:
- could a simple brain such as an earthworm be the result of natural selection?
- could a slightly more complex brain like a crab or crayfish be the result of natural selection?
then move along the chain until you reach a critter that you believe is too complex to be the result of natural selection.
Once you define the break point, you WILL be expected to show why it exists.
