Make a list of the main points you want to have in your presentation. Then work on researching them one by one. Search one topic at a time, find a RELIABLE resource, then find information related to that. Write it all down, then do the next one, etc., etc. Then you can filter out what you do and don't want in it, keeping the important information and ditching the rest. Then you can start putting your presentation together. :)
