Descartes: 1st Meditation concerning skeptical doubts....no Sparknotes answer please!

HELLO: I have just read the First Meditation where Descartes talks about the possibility that we are all dreaming....this stuff is soooooooo confusing! Even supposing that I might be dreaming, what sorts of truths are not doubtful? If anyone is good at this kinda stuff could you explain it to someone like me who is totally confused. Please don't send me the SparkNotes or CliffNotes answer...I just want a clear, plain, concrete, easy to understand answer that makes sense without alot of gobblelegook.... If you understand Descartes, please help me...this philosopher is really hard for me to grasp. Please...no Sparknotes.... Thanks!

Descartes: 3rd Meditation ...no Sparknotes/Cliffnotes answers please!

Hello- I'm still muddling through Meditations (I'm up to #3) and I'm wondering why an "unbeliever" (aethiest) like Descartes felt the need to prove the existence of God in this 3rd meditation....I don't get the purpose it serves in terms of the structure of all of this (Meditation).

3rd Meditation - Descartes...no Sparknotes/Cliffnote answer, please!

Hello: Can someone who really knows & understands Descartes help me? He's tough for me to understand! Question: Why does he (Descartes) need to prove the existence of God in the 3rd Meditation...and what purpose do you think it serves re the structure of the Meditation? I am having difficulty with understanding this man...in fact its painful so I'd be grateful for clarification!
