Unwanted Cube GameOjbect gets generated upon playing any scene?

Hello Unity Community,

This is my first question and I have just begun unity game development, so please forgive me if I incur any formatting, rule, or otherwise any site violations.

Anyway, I am following one of the beginner tutorials, Beginner Fundamentals: Unity Game Dev Course, that takes you through developing a clone of the game "Swords and Shovels." It's a great course, and I would highly recommend it to other newcomers, however, I am having an issue with a Cube GameObject that is randomly being generated when I play any of my scenes.

Here is a screenshot

No matter what I seem to do, I cannot seem to correct this behavior. Once I stop the scene from playing, I delete the cube. However, once I play the scene again, the cube once again gets generated and shows up in the hierarchy. Something peculiar, if I rename this cube to say "RandomlyGeneratedCube" and then play the scene, it's name gets changed back to "Cube" once I play the scene. It appears in different places, there could be an order to where it appears, but I can't figure it out. It seems like its position is random.

I don't know what other information to include. I am a pretty experienced programmer, and I don't believe this Cube is being generated in any of the scripts (I mean that would be a difficult mistake to make accidentally you know?). Has anyone else experienced an issue like this? I possibly hit something unintended within the Unity Editor, I really just have no idea.

Any and all feedback is wanted and welcomed :)
