Science is our enemy?

Hi fellas,you know the planet has been changing for a long time,although some these technological and artificial intelligence,we are still nothing.

Why I say human kind is nothing?

Simple;even we do not use science with truely,we see it like our enemy.If we talk about  concrete things,tell me ;

Why we believe leaders and politicians as God? 

Our planet is getting warm not today but tomarrow it will destroy by global warming effects ( north pole,damage lights,radiations,or unknown new viruses.

We know solutions,but away we do not apply for them?Why it is expensive,only not in global warming in every incidents.Greed......

Why do not we try using full capacity of our brains? I do not mean movies......

At least we can analyse some things,main difference between humans and others.

Obviously key is to learn some things by using science.(Black holes,artificial intelligence,other dimensions,artificial  human body parts and more.

We know future where is in there......
