Oh no, not the dreaded best camera discussion again! *haha*
Any such discussion will be LOADED with personal biases. There is no one BEST beginner camera.
If you're looking for a general camera for day-to-day or travel shooting, just about ANY brand would do -- you have to find out which you prefer. Within a brand, start of light and easy. With Canon and Nikon (and I only mention them because they are the big 2)look a their basic models(Canon 750D/750D, Nikon D3400, I think) with a kit lens, and go from there.
When you go to the store, bring a photo enthusiast friend along for help and support.
Oh, if you can, borrow a set from a friend to try out. It may not be what you want, but will help you determine what features are important to you.
