Right, dude. Please read my post, all of it. I am saying this in the nicest way possible
You have been found out, people know that the screenshots provided aren't yours, we've seen the evidence, we're not dumb. I don't know why people claim other people's work as their own and try to plagerise, but nevertheless its something extremely difficult to get away with. If you're keen to make your game, go ahead and learn, you'll gain a lot more respect that way and people will provide good advice and good comments to help you make your game idea a reality in the end. But your ego is too big, you want the game so much, you want to give people that you've made it and it looks good - saying your work 'is the best', 'or is really good', loses respect and isn't at all modest.
So, you've been found out and don't want to feel like an idiot - denial and further 'arrogance' only digs your lie deeper and worsen things. Luckily this community is forgiving - the truth prospers here, if you apologise and admit you're wrong (and mean it) you will soon find nice comments will follow and maybe even advice about starting your project. By doing this, you're only going to make things hard on yourself, lose respect in this community and get banned, you'll lose your self esteem and basically lose out on making your real game, which will be a shame.
[edit]
I think you'll find the comments that say your project is good etc. is sarcasm.
