Why do people not want to believe logic when it points to what they do not support?

Why is it people don’t want to follow the logic when it is something they don’t care to believe in? I can point to many examples but let us use extraterrestrials. No matter how you slice it we are not alone.

Evolution logic:
If life started here because some primordial ooze was sitting under the right thunder storm at the right time to get zapped by a bolt of lightning causing life to spawn. With all the decillion galaxies out there if it could randomly happen here don’t logic show it can happen in other places? If it did, could it have happened eons before it happened here. Why are people so scared of that logic? They go out of the way to try to prove we are the only ones as if they are scared if there are others out there humans are devalued somehow.

Creationist logic:
Life was divinely created all to a grand plan. Logic shows that why would God (or the entity most call God) would create a great work and then stop? That would make about as much sense as Leonardo De Vinci painting a master piece then putting down his brush never to paint again.

Logic says we are not alone yet people don’t want to believe. Do they actually think they will come use us as food or something?
