which is the oldest veda - #23540

I am trying to understand which is the oldest veda because I've been diving into Ayurveda lately. It's kinda fascinating, honestly! A friend recommended I read some ancient texts, and I've been confused about where to start. I came across mentions of the four Vedas, and I’m just curious—like, which is the oldest veda? Is it the Rigveda or is there something even older that I’m missing? Also, the more I explore, the more questions I have about how these texts are connected to Ayurveda. My mind is racing with info, and I really want to get the basics right. I always thought the Vedas were just these unapproachable ancient scriptures but they're really just the foundation for everything. Any clarity on which is the oldest veda would be super appreciated; I feel like this could change my whole understanding of Ayurvedic practices. Ugh, I just wanna make sure I’m getting the real deal and not some watered-down version! Thanks in advance!
