how do i get out of mama oullo temple i cant get past the entry ways to monkey temple or twin post...and how do i get to the explorer on the side with the idol?please help im stuck?
It sounds as though you may be confused as to which level you're on. From your description it sounds like you're at the Flooded Courtyard (level with a bunch of water and a bunch of pillars sticking up out of the water). The Monkey Temple and the Twin Outposts are two of the three levels you reach from the Flooded Courtyard.
I assume from your question this is the first time you've been there. You can't get to the Explorer until later in the game (requires Pickaxes and is reached via a different entrance from the Jungle Trail). There's also a second Idol and a Shaman on that level but they both require TNT. You WILL have to pass through here again multiple times later, so you may as well grab those at that time.
What you need to do this time is to get yourself up on top at the far end of the Flooded Courtyard. Notice how there are two stone altars, one on each side in the middle of flat lava areas. Go to those and light them both with your Torch. The game will play an animation that will show you where to go next. BTW, after you finish the next level, you will come back through the Flooded Courtyard and it will play another animation showing you where to go then.
