I'll help but you should be using the search bar. Adobe Premiere for PC and Final Cut for mac are the two best but they might be a little bit much for just starting out. They are pretty damn expensive too (>$500) but there are ways to get around that too. If you have a PC you could also buy premiere elements for about $100 which is just a scaled down version of premiere pro but better than most stuff out there. There is plenty of other good software to just search editing software
