Good but has a few cons

I used to be an avid listener and enjoyed the show. But when I came back to the show recently, about a year later, I felt like it was lot more dry and bland. It did not have the same fun stuff, and I don’t like that they have the mystery sound after the credits. While it is a good podcast that is pretty fun, with good knowledge, I wish that could change. Also, just know, that humans did not evolve, but God created man from the dust of the earth, and woman from the rib from him.

Good, but messed up ,

Ya messed up but love the podcast

The chill episode in my fav series the cooking one, it got kinda messed up by the smarty pass ad, yall rewrote over the interview of the guy with the icehouse and it just cuts over it into a random part of the interview and not the whole thing. Please fix that, and yes I know it’s a small thing, but I still love this podcast and think it’s great

C Antoinette ,

Dogs are better than cats🐶✅🐱❌

Do this one: why do all are voices sound different but animals voices don’t? P.S. great show!
