The phrase "early days" refers to a time that is very soon after something has begun, or an initial stage in the development or progress of something. It suggests that there is not yet enough information or experience to make a full assessment, and that further observation or reflection is needed before drawing conclusions. The term can be used in various contexts such as when referring to a new project, relationship, job, or venture - indicating that it's still too soon to tell how things will turn out, but there is hope for the future.
