Sometimes my five year old little girl asks me too many questions and I don’t know how to answer them. How do I evade them?

Why would you want to evade her questions? If you don't know how to answer them, try searching for the answer together with her. Both of you will learn something in the process. If her questions don't make sense and are plain annoying which makes you want to evade them, you could reply her with "Well, then why don't you find out yourself?" and throw her an encyclopedia. Maybe you need this book. http://www.barnesandnoble.com/w/asapscience-mitchell-moffit/1119886097
