I can easily argue the opposite of your assertions, simply by picking different definitions.

The "stars and planets" do not influence peoples' lives through the seasons, only the Earth and its relative position to the Sun do, and when someone talks about the "stars and planets" in the context of astrology, they mean other stars and planets besides the Earth and Sun.

Dinosaurs do not co-exist with humans, and never have: "birds" are the distant descendants of some of the "dinosaurs", but are not part of the same group. (I'm pretty sure any dictionary definition of "dinosaur" does not include modern-day "birds".)

From Wikipedia:

> Birds are feathered theropod dinosaurs and constitute the only known living dinosaurs.

Bird are in the dinosaur clade, ie the biological group defined by the dinosaur family.

Birds are dinosaurs in the same way that humans are mammals.

I'm not going to argue with your clear reference but I will reference this article: https://askabiologist.asu.edu/questions/birds-dinosaurs-rept... which adds a bit of useful context.

"So a reptile is any animal descended from the original group called reptiles. Both birds and mammals share ancestors sometimes referred to as reptile-like animals (Reptiliomorpha), but it's not very common for people to talk about mammals as reptiles."

That’s because mammals aren’t reptiles:

Mammals are from Synapsids[0] and dinosaurs (and modern reptiles) are from Sauropsida[1] — with the commonality being that amphibians split off first [2]. We can draw disjoint clades, which we cannot do for birds and dinosaurs. Beyond that, you’re just talking about tetrapods in general [3]. Reptiliomorpha has multiple names, precisely due to this — eg, pan-amniota.
