recommendations for learning about religion from scratch

I’m someone who was baptized Christian as a baby, was vaguely told about God as a kid but never even read the bible or went to church. I don’t know what I believe in exactly, I just don’t feel like I’m an atheist. I’ve learned a bit about Christianity and Islam and Judaism through friends who’ve taken the time to tell me what they know and believe, but sometimes I feel so lost when I’m being told history. Are there any books or other resources people recommend to teach me the history of religions? Or even just your own religion- I’m really open to anything and want to learn.
