Not in this state. The forms we take are conditioned by our karma. One aspect of the human form in this world is the inability to remember previous lives until extremely high spiritual states are attained, and even that latter bit is questioned by some.
The karmic effects and impulses continue on, invisibly. The memories (and much of the personality) die with the body. This is not a satisfying answer to some, but it's the most realistic.
And you could also ask how you are even reincarnated to a human when the probability of being a virus/bacteria is several magnitudes larger?
That discussion could go on for days: which lifeforms are sentient and which not, whether human birth makes future human birth more likely, etc. For sure: human birth is rare. Buddha compared it to an ocean with a wooden ring on it, with a turtle who rises to the surface once every 100 years. Human birth is as rare as that turtle surfacing inside that ring.
Bullshit. We don't know how long life lasts, nor whether supernatural purposes or intentful[0] beings exist, nor what (if anything) is after. That does not mean there is "no purpose" to it. It is its own purpose.
Personally, I am most in line with Buddhism and think reincarnation is likely, and that mind (consciousness) itself is a first-class citizen, but existence doesn't have to be eternal to be meaningful. In fact, if a finite existence were meaningless, then an eternal one would be meaningless and infinite, which would be far more undesirable than death.
[0] "Intentful" is not a dictionary word, but nothing else captures what I am trying to say so I am justified in making a word up.
