Sure you could; those are pretty mundane and ordinary things. If you really had to you could take a photo of your breakfast and show it to me. You can tell me where the gym is that you attend and also send me a photo. There are plenty of ways to verify such ordinary things, if you had to. Besides, these are just boring everyday claims that don't affect anybody else all that much.
Claims of Gods and afterlives are a tad different though - in that if they were true, would affect everyone on the planet in a major way. I mean, we're basically all immortal, under your view. That's a bit more significant than what you had for breakfast this morning, wouldn't you say? Extraordinary claims such as existence of afterlives and spirits require some pretty good evidence, don't you think? Or do you just take someone's word for it if they tell you they saw a pixie walking down the sidewalk? Or that they were abducted by aliens?
There must be a way to test these claims and figure out which are true and which are false ... hmmmmm ....
