Your thesis statement and introduction should function as a road map for your reader which lets your reader know what to expect in the paper. Follow the outline of your thesis for a successful paper. Evidence goes here. Use specific details. Conclusions wrap up the idea of the essay and provide an overview of the points you make in the developmental paragraphs.
Conclusions restate the thesis in a different way.

It has lead to the invention of many new products that have made life on Earth easier and better.
