Making the world more like the heaven- can you please correct me

Making the world more like the heaven:

The world can never be a heaven because whatever we create or make, we need to follow the laws of nature. We can't change the laws of nature. What we can is just that we can make use of our ideals and the behaviour of matters and energy. However, the following are the five things which if them we can give people for free, we would have more freedom on earth:

Free-food: We know everything is energy and there are many kinds of energy which are so much in universe. We eat food to have energy that helps us grow and keep alive. If we can create a machine that can transform energy into food, we wouldn't have the lack of food any more. We also don't have to do jobs or business to make money for food.

Sex-robot: If we can give everyone a sex robot, we would no longer have to get married and give birth to children.

Safety: Safety is a must to have. We can also create robots for our safety.

Cloth: We can make robots for making cloths.

Perfect-translator: Making a translator that would perfectly translate one language into another could free us from leaning a new language. We no longer have to struggle to learn foreign languages like now. We can communicate with any countries' people so freely.

Our world can never be a heaven, but doing these five things, we can take our world more closer to heaven.
