It's impossible for an actual Bitcoin to be forged. It can only be created when it is mined, and all nodes get a copy of who received that mined "block".
If you try and create "lots of money" on your computer, then initiate a transfer to another person, your "fake bitcoin" will dematerialize before it even reaches the other person. The transaction has to be approved by many nodes on the network, all of which have a copy of the ledger (all transactions that have ever occurred, verifying who has what bitcoins)
