How to make a logo without copyright?

I'm curious about creating a logo without any copyright concerns. Could you please elaborate on the steps I should follow to ensure that my design is free from infringement? Are there any specific guidelines I should adhere to while creating the logo, such as avoiding common designs or incorporating unique elements? Also, what tools or software would you recommend for designing a logo that is both original and copyright-free? It's important for me to understand the legal aspects involved, so could you explain how I can verify that my logo doesn't infringe on any existing copyrights? Thank you for your assistance in this matter.
