ちぇよよん

明日、英語で発表があります。それの原稿を作ったのですが、文法に自信がないのでちゃんと伝わるかチェックと訂正をお願いしたいです。

Today,I’ll tell you about Nasca Lines.
they were created by the Peruvians about 2000 years ago.
The purpose of them isn’t clear.
There are various sizes.
For example, a hummingbird is about 96 meters.
the pelican is about 285 meters and It is said to be the largest drawings of animals in Nasca Lines.
It was drawn using the expansion method.
This is an example of expanding 3 times.
I think many people don’t know about Nasca Lines in detail.
However, people will be interested in them by knowing that many old paintings still remain.
I think it's also attraction that there are still many mysteries.
Please consider to feature Nasca Lines on TV program.
