Default Oil Leaks

Here is where I can see oil dripping from these 2 spots. When looking from above the engine there is absolutely nothing wet that I can see. When looking around from underneath I don't see anything wet above these areas that would indicate anything obvious that's leaking. Just these 2 spots have drips and that's literally all I can see. I am no mechanic but I have had no problem finding leaks in the past until these. Its either something very hidden and probably a PAIN or im just missing something here??

Thanks for any suggestions!

It does look like engine oil is leaking. To confirm, you can monitor engine oil level. Keep a quart handy as if you go below min, the engine will be a toast.
I can't identify exactly, but it seems like the oil is coming out of a weep hole. If the weep hole is between the engine block and the transmission then it is the rear-main seal that is leaking. [since the engine is transverse mounted the rear would be the driver side].

I agree with Salim.

If you want to see the leak better, I like to buy 4-5 cans of brake cleaner and spray liberally on the area(when cold engine only)- it cleans oil and grease well.

Thats what I was worried about because I couldn't see it being anything else except the rear seal. Thank you.

Have you ever tried this stuff: https://gobdp.com/product/rear-main-sealer-00234/
It's supposed to work well for rear main seal leaks. Scotty Kilmer is also a big proponent of it, FWIW.
