I agree with all that. That is what I commend you for. But it also leads you astray when you presume that you have done due diligence but haven't. The polar shift concerns are an example. Most of the data you cite in support of timelines is flat out wrong by many orders of magnitude. Like how long the solar system takes to orbit the galaxy.
If amended to how often the solar-system crosses the galactic plane it is still wrong.
I am not saying none of it can happen, I am saying your reasons for believing it are false. Believing the right thing for the wrong reasons is barely better than believing the wrong thing for the wrong reasons.
Trust is everything. Find good mentors. You aren't going to get there on your own. I know I can't.
