Imagine if you had never seen winter before,no thunder etc nobody had told you about the four seasons, so of course when the winter “ice-age” came people panicked because they did not know how long this season would last and if there were enough food for all the people.
The Norse Gods is simply the forces within nature which were created through fear of the unknown but also to warn the future generations about the spirits within nature, some were seen as necessary but feared at the same time.
This is why they made sacrifices to please the Gods each year because they believed it worked and it did because all seasons comes every year.
Back then they did not think like we did and did not have the same knowledge.
That being said they developed better knowledge and understanding of nature and it’s forces/Gods back then and knew how to respect and treat mother earth.
I personally think that they did not fear the Gods like in a religion and is not to be confused with any religion.
Superstition is a more suiting word which probably ruled in the very beginning.
Talking about the Gods in Norse mythology is like deciphering a belief system they used to learn their kids to treat and respect mother earth and her forces.
To put it simply : Those who claim that our ancestors were god-fearing religious people are wrong I’d say and after reading several books on the subject I just had to write this.
How many books do we need on the subject btw? It’s not that hard to understand if explained properly.

They spoke,thought,behaved in a totally different way back then so it’s important to keep in mind while studying Norse Mythology to keep in mind that this was the first “documented” happenings on earth and that most things were written as myths when language became a thing.
Before that they had only word of mouth and possibly signs/runes to pass on the message.
So they were not dumb people like some say, they invented our language,traditions and the only way we know how to stick to reality : Runes and later the alphabet.

If you think about it they were not really that primitive compared to us today, they were harder,smarter in life and used the “right” more simple ways of living.

Today most people don’t know how to hunt anything so I dare you to learn the old ways because they will and should be useful once again.
To answer the title question, no we don’t need more info, we need to decipher it ourselves and learn how easy life can be if you follow some guidelines.
I could go on but I will keep it short because that’s all you need.
Mark my words and good luck!
SHTF soon enough…
