So there's no definitive answer on why the Forerunners rose up against the Precursors, however I would like to try and put together a plausible theory based on the information we have been given. Now I understand that some of these accounts may be half-truths or misunderstandings, since the Primordial isn't the most trustworthy character and its viewpoint being skewed since it's not omnipotent and only has certain information and the Domain has been stated to rewrite its own information like actual memories while the Librarians viewing of the memories of the ancient Forerunners abandoned in Path Kethona may be skewed due to unknown information on their part.

But considering it's all we have, i'm going to give it a go:

The Precursors left evidence of there existence in the galaxy after seeding life and retreating to Path Kethona but left a few of there own behind to watch over there creations for one worthy enough to be given the Mantle. The Forerunners would eventually rise and begin to explore space and fine these remnants and the Mantle. They would claim it and police other species, which would draw the attention of the Precursors left in the galaxy to judge whether they were actually worthy of holding it. The Forerunners would be deemed unworthy and would eventually lash out and kill a few Precursors causing the Kethona Precursors to arrive in bulk to the galaxy to determine their fate. Eventually, the Forerunners would be chosen to be eradicated and the Mantle would be passed to their genetic cousins, Humanity should they pass some form of testing. The Forerunners would learn of this and in both jealousy and a need to protect themselves, strike back at their creators forcing the survivors to flee to Path Kethona while some flee to Netherop.

Obviously this isn't canon but it's the best with what I could given what we know.

So how advanced were Humanity during the Forerunners rebellion against the Precursors?

Both species were stated to have been seeded around 15 million years ago and had evolved during those 5 million years with Humanity evolving from Primates and the Forerunners evolving from whatever they evolved from. However, what I don't get is how the Forerunners were so advanced compared to Humanity despite being seeded at the same time.

The Forerunners were spacefaring for 9 million years before Humanity had been reported too, with their first reported civilisation arising 1.1 million years ago so i'm just confused as to how it took them so long.

So me and my friend rarely see each other these days. The last time we did was back in November, I think. I brought it up to her the other day and now i'm wondering if i'm in the wrong.

For some context, we used to hang out as a group with our other 3 friends but 2 of them stopped talking to us so now it's just me and my current 2 that I still talk too.

My friend works 5 days a week and usually has 2 off. She usually has plans with everyone else except me. For example, she spends time with her family etc, which I get but then she'll hang out with her other friends (one of which she works with) or my other friend (who is also her boyfriend) like all the time on her days off. She has this one friend that lives far away but I swear she see's like 2 a month.

Now this wouldn't bother me usually, people have lives and personal stuff. But lately i've come to realise that i'm not being considered anymore or that she just doesn't want to hang out with me. I don't mean that to come off snotty or spoiled but she's says that she try's to make time for everyone. Yet when I ask her to hang out on a day we both have free, she'll say one of three things: say she's already got plans with someone else, say yes to hang out when we're both free and then the day before say she already has stuff happening that day OR she just won't get back to me on a time and place to meet until the day is over.

I've brought this up with her and she says that i'm being mean and trying to make her feel guilty, which i'm not. I'm not trying to seem like an asshole but now I feel like one because she feeling bad about it.

How would the Carja (and the sun-priests) take it if the reigning Sun-King died and any male heir died (to some sickness) and only a daughter was left to rule? How would they explain it?

I think they would probably say that the time of twilight is upon them and their doom is near (similar to the Carja-in-Shadow under Itamen) since they didn't have a true Sun-King
