How do I edit text without selecting Mesh?

I’ve been having trouble all the time editing this text, I am pretty new with Blender… I want to edit the selected text by clicking TAB, but it rather shows meshes and black lines…


I really don’t know how to edit the text rather than getting these black lines.
Excuse my Noobiness

The object looks like it’s a mesh object rather than a text object.
To edit the actual text in edit mode it would need to be a text object. You would have to manually move each vertex/face to the look you want or delete it and add the text again (Shift+A / Add / Text)
