does Having arrived at the conclusion, and anouced that there is no creator/god leave you in a vulnerable mental state?
On the one hand you have no father,
on the other hand, you are, with your fellow 'believers', the most intelligent beings in the cosmos, the multiverse , barring other more advanced civilisations beyond the horizon, of course.
One way or another that can be an unstable untenable situation, so you need more COMFORT and SUPPORT.
because you do have a father, have his genes, and there just might be higher intelligence out there.
