How do you buy BCH?

Excuse me, could you possibly explain the process of purchasing BCH? I'm quite new to the cryptocurrency scene and am a bit overwhelmed with all the options and procedures. Could you break it down step by step for me? First, where do I even start? Do I need to create an account somewhere? And once I have that, how do I actually go about buying BCH? Is there a specific platform or exchange that you recommend? Also, are there any fees or commissions involved in the process? And finally, how do I ensure the safety of my investment? I'd really appreciate your guidance on this matter.
