So show me support for the magic stars needed to produce the event according to their own theories? Or should we take it by faith only? Ha
No you shouldn't. You should and are expected to question it.
Unless you have enough background knowledge to support your questions, you may look a little silly to those who do but that is ok. that's the basis of learning.
The same skepticism of science tends to spill over onto theology/religion. You get into the habit of questioning everything. There is nothing particularly biased in questioning religion. It's how science deals with everything.
