Beginner looking to start investing, need ETF advice

Hey everyone, I’m 14 and have been earning some money from a part-time job. I currently have about $2,500 saved and plan to invest roughly $650 each month. I’m really new to investing and still learning the basics. I’ve heard about VAS but don’t really know much about it. I’m looking for a simple ETF recommendation that’s good for a beginner like me. Any tips or advice would be awesome! Thanks!
