This message is proof that you actually did not read. Or rather you have only read, but not understood. Read it all over again and again. Take your time. The answers are all there. I don't have time to give you the whole "sermon" also because it's already there.
He's right, those questions are not answered in ToZ. If you disagree, find me the parts where they specifically address these questions and quote them here. It's better instead of insulting people who ask these questions to not reply at all and leave them to someone else.
The first is: I have enourmous respect of the gods, but if the gods are advanced and evolved beings why should we give them energy? I understand they are our teachers but,
Don't they have enough energy on their own? They have spaceships, technology and so on but they need us? It seems absurd to me, it seems to me rather that we serve them and not them to us, (I'm not a troll, I'm seriously curious).
They do have enough energy of their own. People give them energy as a token of gratitude, not because the Gods need it. It's just like offering someone a gift for something they did for you.
the other question always concerns the gods,
we too are potentially like them,
science has proven that our consciousness can manifest siddhis or powers such as foresight, expanded knowledge and so on and also that we are the entire universe, so why do we need external gods? can't we do it alone?
We also have latent musical and mathematical abilities. Why do we need to learn how to do math or play music in schools in universities? Why do we need professors and teachers?
It's the same thing as the Gods. We don't know how to awaken these abilities, because they have been dormant for a long time. We need someone to teach us. The Gods have already awakened these abilities and use on a daily basis, so they can teach us how to become like them. All those advanced meditations and teachings in ToZ that help us become spritually stronger came with the help of the Gods.
The ToZ also says that when you advance far in the occult and develop your abilities, you'll come to the attention of advanced beings who will feel threatened by your advancement so you'll be attacked a lot. For this reason, we do need protection, and this comes from Zeus and the Gods. I've seen advanced occultists who weren't aligned with Satan had terrible things happen to them from enemy attacks, the mild ones being aging prematurely and losing their hair.
Most people I encounter come from Christianity and want to worship Satan like the Christian god and aren't interested in things like chakras and meditation. You seem to take to the other extreme where you're saying that we should use the knowledge that came from the Gods without acknowledging them at all. Both extreme viewpoints are harmful for your progress.
The last doubt, in ancient texts there is everywhere talk of animal sacrifices, even Greek and Roman historians talk about it or ancient poets, how is it possible?
Most "sacrifices" could be better described as "ritual feasts". Greek and roman "sacrifices" were just like that, they just did a ritual to a specific god to offer an animal they slaughtered before they ate it. There were ritual executions of criminals that Christians twisted and claimed they were "human sacrifices".
how could a people who appeared a few thousand years ago than us be able to infiltrate hundreds of different cultures and rewrite their texts even on the islands?
It's not just humans, there are enemy alien beings who are behind the enemy programs. There were non-Christian cultures who were in contact with such beings. For example, the Aztecs were corrupted by such enemy beings and started performing human sacrifices in the 15th century. They had the same apocalyptic beliefs like Christianity, as they believed they were delaying the end of the world by offering gruesome human sacrifices.
