how bout that stuff

 layer 3 then 1 then layer 6, then layer 2 then layer then layer 5 then 4 

i think layer layer 3 is the youngest because it gose threw all of the rocks. then layer 3  then layer 6 becuase its under it layer 2 because it gose threw all the layers but 3,1 and 6

 then 5 then 4 

Earth Older than 6,000 Years Old!

one reson is probly beacuse plates and layers all start out flat but it probly took years for some of them to bed and probly a lot of heat beacuse if u just try to bend rock it will break you have to do it slowly. there are also thousands of layers on some of the rocks and like a tree each layer shows 1 year old it is so that could also be a reason why  the scientist suspected it was older then 6,000 years.
