Does the number of Confirmation relate to the number of bitcoin nodes?

[supermankid]

My assumption is that the confirmation can only be done by a node and the number of confirmation means total amount of node that have verified that transaction.
If this is the case, will the first transaction of the bitcoin has the highest number of confirmation?

Miners are the ones that confirm tx, not the nodes. Nodes validate transactions.

The number of confirmations a tx has after its first confirmation simply means the number of blocks that have been mined on top of the block that the tx was mined in. Let's say your tx has 10 block confirmations, it means that 9 blocks have been mined on top of the block that your mined tx was included in.

That's right. In other words you can think of the "number" of confirmation as the "depth" of that transaction into the blockchain or the distance the block containing that transaction has from the tip.

Miners confirm transactions on the network. Nodes validate transactions and store transactions, blocks in their nodes.

Each block on the blockchain is like a layer of soil, one above another. If your transaction is confirm by block #100,000, later blocks will be added on top of the #100,000 block and will increase security of your transaction, make it more irreversible.

How many Bitcoin confirmations is enough?

mining POOLS collate transactions into a batch(block) of transactions according to the rules of the code of the network consensus
which that block also contains an identity of the previous block to link(chain) blocks together
miners(asics) hash an strong identity for that newest block.

nodes reseicing a hashed block, validate blocks to ensure the collated transactions meet the rules and if they pass they keep the block allowing the next block to be built ontop of it and linked to it

a confirmation number is how many blocks exist and have been built ontop of the one containing the transaction in question

EG if a transaction is in block 800,000 and the current block height is 802,871 then it has 2871 confirmations

Yes, you are on the right track!  The number of confirmations in a Bitcoin transaction refers to the number of blocks following the block containing the transaction in question.  Each block must be validated by the network of nodes, so the more successive blocks validate the transaction, the greater the confidence that it has been accepted by the network. However, the number of confirmations does not represent the number of nodes that have verified the transaction, but the number of successive blocks that have been added to the blockchain. The first Bitcoin transaction didn't have more confirmations because there was nothing previous to connect to, but over time and as successive blocks were added, it accumulated more confirmations.

All transactions belonging to one specific block will have the same number of confirmations. When the next block is confirmed (mined), all transactions in the previous block will have one more confirmation, and so on. This is where the name "Blockchain" comes from, which literally means a series of blocks linked to each other.

The Genesis block had only one transaction which was made by Satoshi in 2009, so that transaction in block 1 is going to have the most confirmations in the BTC blockchain because all the other blocks mined since then until now have been mined on top of it.

Thanks to all for clear answers. One more curiosity closed on my bitcoin journey.

Bitcoin journey do full of such questions which we should ask other wise one day you will become a senior member and afraid to ask them (i am not talking about any other senior member). hehe. But still, asking question sometimes work as the reminder to remind you the knowledge which is getting corrosion somewhere in your mind.
