Is there a way of creating a transaction that is accepted by ompanies like coinbase after you confirm it manually on two different computers.

What do you mean by confirm it manually?

And what does your title have to do with the topic?

Are you asking if its possible to manually submit a transaction to the network stating you actually own 10000000 Bitcoin?

Absolutely. Can you have 2 different manually computers confirm it? Absolutely.

Will that do anything?

Absolutely not.

This really doesn't belong in Dev Discussion.

You seem to have problem in understanding how bitcoin works. I'd suggest to start reading from here: https://en.bitcoin.it/wiki/Help:Introduction

If you were to manually input transactions on my bitcoin-qt and put it on two computers and then get two computers to authorise the transactions due to how it is mined. Which would mean you were earning bitcoins by coding in transactions into blockchains which could be confirmed by computers through the mining process.

You mean double spending transactions? Even if you broadcast two transactions with same inputs, one will be rejected. If both are included in a block by a miner, then that block will be considered as invalid by all nodes following protocol, regardless of your node and miner's accepting it as valid block.

NO. ABSOLUTELY NOT. Please read some more about Bitcoin. You would be creating a fork of the blockchain which would not be accepted by the Bitcoin network. Your transactions would not be valid since a previous input is not valid and such a plan would not work.

Also, please read up on Bitcoin, preferably the white paper by Satoshi. Miners do not authorise transactions, they simply verify transactions (which all full nodes do) and include them in blocks securing them with cryptography to prevent double spends.
