And The Story Continues

The first thing I realized was that there was too many sons with difficult names. I know I'm supposed to be analyzing the bible, and I will get to that, but first I will ask the question "Why?" Did like everyone back then have 15-20 kids each? I mean seriously?!
But back to seriousness.
In chapter 11, it explained how the tongue of the people was all one language and how people began to build a tall tower to reach into heaven. The tower made God angry and He scattered it across the ground (although it doesn't neccassarily say that) and then He created different speeches for everyone so they would not understand each other as is stated, "Go to, let us go down, and there confound their language, that they may not understand one another's speech." So I'm guessing that day that God created over 3,000 different languages, which is rather insane if ask me. That's a lot, but I guess he was upset. What I can't seem to grasp is why did he decide to punish them by making them not able to understand each other? What I mean is, why did he see this as the worst punishment? Also, I though God destroyed the tower that was being built to "go" to heaven with an earthquake, so why doesn't it say it clearly in the Bible? I'm starting to wonder if whoever wrote this was trying to make it impossible to read and understand well.
Now, I don't understand why Abram wanted his wife, Sarai, to be seen as his sister. It tricked the pharaoh, and when he found out the truth, he sent them away. So I don't understand, why lie in the first place and have her seen as "fair"? Perhaps it did explain it, but I'm just not understanding. Was it so they would become rich and then when they were sent away, they would have many beautiful and rich things to live off of so they could travel further? And another question, why is God haveing Abram and his family travel all over? Is it so Abram can preach people in different parts and spread God's word? Maybe when it says, "built there an altar unto the LORD" it is talking about in a way, a church being built, or something like a church, to preach the gospel.
Now I'm starting to wonder why in the world would the LORD want Abram to count all the stars. Isn't that like more than impossible? There's too many! So why would the LORD want to prove Abram to prove his repentance by counting stars?!
Now, even crazier, Sarai had her maid Hagar bare her a child! It may not seem crazy, but what if I told you that Sarai had Hagar go to Abram and have a child with him? Yeah, you heard me right. Instead of having Hagar baring a child with another man, Sarai had her maid bare one with her own husband! Crazy. I would never do such a thing!
So far, reading these bible stories, I'm starting to become convinced that everyone's crazy. Just a thought.
