I've been "digging" (investigating in earnest) for a few years now (for my whole life really, but more properly focused since 2020). I've written thousands of pages on this topic (including a book). My investigation (and the associated follow up hypothesis) has been focused on "how long has that single entity been controlling the world through the same methodology?" That it has been controlled by a single entity is well established and in my book. The follow up investigation of "how long" is the hypothesis.

I can establish that the single entity (or very closely tied group of entities, knowingly working towards a single goal) has been controlling the world from the shadows, is beyond a reasonable doubt, and it has been going on since at least 70AD, with very few reasonable doubts since 500BC. From there, I have found several evidence chains that suggest it has been going on (from the same group) from as long as 4000BC, with some evidence suggesting it has been going on as long as the Flood (around 10,000BC).

Reasonable questions of what happened before that gets really muddy (pun intended). But there are hints that the Flood may have been an orchestrated event INTENDED to bring about the world we have today (i.e. it was a power play).

Did the entity (human genetic group? alien group?, extra-dimensional (AKA "spiritual") entity or group? all of the above?) cause the Flood, or did they just take advantage of the situation afterwards? I don't know if it's possible to know for sure (different evidence suggest opposing conclusions). Like I said, it gets way too muddy. If you have any specific evidence (that I haven't already found, or that you may have specific insights for), that would be helpful in my investigation. "Keep digging" on the other hand is... not overly useful.
