Can I buy ETH with BNB?

Excuse me, I've been hearing a lot about cryptocurrencies lately and I'm quite interested in getting started. I've read that ETH and BNB are two popular options, but I'm not quite sure how to proceed. Could you possibly clarify something for me? I'm wondering if it's possible to buy ETH using BNB. Is there a specific platform or exchange that allows for such a transaction? I'm a bit new to this and would appreciate any guidance you could offer. Thank you in advance for your help!
